Information Needed for Configuration

Gather the following information, depending on your planned network scenario, before configuring your network:

  • If you are setting up an Internet connection, gather the following information:
    • PPP client name that is assigned as your login name
    • PPP authentication type: Challenge Handshake Authentication Protocol (CHAP) or Password Authentication Protocol (PAP)
    • PPP password to access your ISP account
    • DNS server IP address and default gateways
  • If you are setting up a connection to a corporate network, you and the network administrator must generate and share the following information for the WAN interfaces of the routers:
    • PPP authentication type: CHAP or PAP
    • PPP client name to access the router
    • PPP password to access the router
  • If you are setting up IP routing:
    • Generate the addressing scheme for your IP network.
    • Determine the IP routing parameter information, including IP address and ATM permanent virtual circuits (PVCs). These PVC parameters are typically virtual path identifier (VPI), virtual circuit identifier (VCI), and traffic-shaping parameters.
    • Determine the number of PVCs that your service provider has given you, along with their VPIs and VCIs.
    • For each PVC, determine the type of AAL5 encapsulation supported. It can be one of the following:

AAL5SNAP—This can be either routed RFC 1483 or bridged RFC 1483. For routed RFC 1483, the service provider must provide you with a static IP address. For bridged RFC 1483, you may use DHCP to obtain your IP address, or you may obtain a static IP address from your service provider.

AAL5MUX PPP—With this type of encapsulation, you need to determine the PPP-related configuration items.

  • If you plan to connect over an ADSL or G.SHDSL line:
    • Order the appropriate line from your public telephone service provider.

For ADSL lines—Ensure that the ADSL signaling type is DMT (also known as ANSI T1.413) or DMT Issue 2.

For G.SHDSL lines—Verify that the G.SHDSL line conforms to the ITU G.991.2 standard and supports Annex A (North America) or Annex B (Europe).

  • If you are setting up 3G:
    • You must have service availability on the Cisco 819 ISR from a carrier, and you must have network coverage where your router will be physically placed. For a complete list of supported carriers, see the data sheet at Cisco 3G Wireless Connectivity Solutions.
    • You must subscribe to a service plan with a wireless service provider and obtain a SIM card.
    • You must install the SIM card before configuring the 3G Cisco 819 ISR. For instructions on how to install the SIM card, see Cisco 800 Series see Configuring Cisco EHWIC and 880G for 3.7G (HSPA+)/​3.5G (HSPA)
    • You must install the required antennas before you configure the 3G for Cisco 819 ISR. See Table 1 for instructions on how to install the antennas:

    • You must check your LEDs for signal reception as described in Table 2-1 .
    • You should be familiar with the Cisco IOS software. See the Cisco IOS documentation beginning with Release 12.4(15)T or later for Cisco 3G support .
    • To configure your 3G data profile, you will need the username, password, and access point name (APN) from your service provider:

After collecting the appropriate information, perform a full configuration on your router beginning with the tasks in Configuring Command-Line Access.

Configuring Command-Line Access

To configure parameters to control access to the router, perform the following steps, beginning in global configuration mode:

SUMMARY STEPS

    1.    line [aux | console | tty | vty] line-number

    2.    password password

    3.    login

    4.    exec-timeout minutes [seconds]

    5.    line [aux | console | tty | vty] line-number

                Configuring ADSL or VDSL on Cisco 860VAE and 880VA Multimode ISRs

                This section contains the following topics:

                Overview of Cisco 860VAE, 886VA, and 887VA Multimode ISRs

                The Cisco customer premise equipment (CPE) Cisco 866VAE, 867VAE, 866VAE-K9, 867VAE-K9, 886VA and 887VA integrated services routers (ISRs) support asymmetric digital subscriber line (ADSL) 1/2/2+ and very high speed digital subscriber line 2 (VDSL2) transmission modes, also called multimode.


                Note


                The 866VAE and 886VA support xDSL over ISDN. The 867VAE and 887VA support xDSL over a plain old telephone system (POTS).

                The default CPE operating mode is auto. Auto mode means that the CPE trains up to the mode configured on the digital subscriber line access multiplexer (DSLAM), ADSL1/2/2+, or VDSL2.

                The following examples assume the DSLAM is configured in either ADSL2+ mode or VDSL2 mode, and the CPE is configured in auto mode.

                Figure 1 shows an ATM WAN or Ethernet WAN network topography.

                Figure 1. Example Topology

                1

                Fast Ethernet LAN interface or

                Gigabit Ethernet LAN interface

                2

                ATM WAN interface—ADSL 1/2/2+ mode or

                Ethernet WAN Interface—VDSL2 mode


                Note


                A DSLAM in Layer 1 mode may be configured for auto mode. A DSLAM in Layer 2 mode must be configured for ATM mode or packet transfer mode (PTM).

                Note


                Cisco 886VA and 887VA allow a maximum of four permanent virtual circuits (PVCs).

                Note


                Cisco 866VAE, Cisco 867VAE, Cisco 866VAE-K9, and Cisco 867VAE-K9 ISRs allow a maximum of two PVCs.

                ADSL2/2+ Annex M Mode on Over POTS VDSL2/ADSL Multimode Annex A SKUs

                Annex M is an enhancement of the G.992.3 standard that doubles the upstream bandwidth by "borrowing" 32 additional tones from the downstream frequency range. This feature enables service providers to provision symmetric data rates for ADSL2 and ADSL2+ services with data rates up to 2 Mbps.

                Cisco IOS Release 15.2(1)T adds support for enabling Annex M data structures on Cisco 887VA platforms and Annex A data structures on Cisco 887VA-M platforms. This features allows both Annex A and Annex M structures to be run on the same platform with a performance tradeoff for the annex that is not optimized for the device. With this feature implementation, the modes supported on Annex A platforms are the same as the modes supported on Annex M platforms (887VA-M and EHWIC-1DSL-VA-M). When digital subscriber line access multiplexer (DSLAM) supports Annex M, Annex M mode takes precedence over Annex A mode.


                Note


                Cisco 867VAE and 867VAE-K9 require Cisco IOS Release 15.1(4)M2 or 15.2(2)T or later to use this feature.

                For information on configuring Annex M data structures on Annex A platforms, see the, Enabling ADSL2/​2+ Annex M Mode on Over POTS VDSL2/​ADSL Multimode Annex A SKUs.

                Configuring Seamless Rate Adaption

                ADSL connections can be dropped due to a number of reasons, such as crosstalk, changes in noise margin, temperature changes, or interference. ADSL2 addresses these problems by adapting the data rate in real-time. Seamless rate adaptation (SRA) enables the ADSL2 system to change the data rate of the connection during operation without any service interruption or bit errors.


                Note


                These features are not currently available on the 866VAE, 867VAE, 866VAE-K9, and 867VAE-K9.

                For information on configuring SRA, see the Enabling Seamless Rate Adaption.

                Configuring UBR+

                UBR is typically used for data communications applications, such as file transfer and email. UBR is a best effort service and is the lowest class of service in the hierarchy. There are no guarantees to the actual bandwidth allowed. Therefore, UBR virtual circuits (VCs) are susceptible to a large number of cell drops or a high cell transfer delay as cells move from the source to the destination. UBR has no bounds on Cell Delay Variation Tolerance (CDVT) and is only a best effort service.

                UBR+ is a special ATM service class developed by Cisco. UBR defines only peak cell rate (PCR); however, UBR+ defines a minimum guaranteed cell rate (MCR) and (on the switch) a cell delay variation tolerance (CDVT).


                Note


                On Cisco IOS versions 15.2(1)T and later, UBR+ is compatable with Cisco Multimode 886VA and 887VA routers.

                Note


                These features are not currently available on the 866VAE, 867VAE, 866VAE-K9, and 867VAE-K9.

                For information on configuring UBR+, see the Configuring UBR+.

                        Example:
                        Router(config)# controller vdsl 0
                         

                        Enters config mode for the VDSL controller.

                         
                        Step 2 operating mode {auto | adsl1 | adsl2 | adsl2+ | vdsl2 | ansi}

                                  Configuring the Training Log Using the CLI

                                  When you initiate the training log capture using the debug vdsl 0 training log on the Cisco 866VAE, Cisco 867VAE, Cisco 866VAE-K9, and Cisco 867VAE-K9 ISRs, the training log file opens. Any messages that are generated are buffered locally and are written to the training log file at 5k bytes per interval. The messages are not written all at one time, as in previous software versions that supported the training log capture feature.


                                  Note


                                  A maximum log capacity of 8MB (approximately 1 hour of capture) exists on the Cisco 866VAE, Cisco 867VAE, Cisco 866VAE-K9, and Cisco 867VAE-K9 ISRs. Because of this capacity limitation, when the entire log collection exceeds 8MB, the log capture is automatically terminated.

                                  Note


                                  Cisco 866VAE, Cisco 867VAE, Cisco 866VAE-K9, and Cisco 867VAE-K9 ISRs do not support the continuous training log autostop feature.
                                  Capturing the Training Log

                                  By default the training log is saved to flash:vdsllog.bin.

                                  To start the training log capture, use the debug vdsl 0 training log command.

                                  Router# debug vdsl 0 training log
                                  Router#
                                  

                                  The following confirmation is displayed:

                                  Training log generation started for VDSL 0
                                  
                                  Halting the Training Log Capture

                                  To stop the training log capture, use the no debug vdsl 0 training log command.

                                  Router# no debug vdsl 0 training log
                                  Router#
                                  

                                  The following confirmation is displayed:

                                  Training Log file for VDSL written to flash:vdsllog.bin
                                  
                                  Displaying the Training Log Status and File Location

                                  To display the training log status and file location, use the show controller vdsl 0 command.

                                  Router# show controller vdsl 0
                                  Router#

                                    Specifies the DSL line rate for the SHDSL port. The range is 192 to 2312 kbps. The default is auto (negotiated between the SHDSL port and the DSLAM).

                                    Note    If different DSL line rates are configured at opposite ends of the DSL uplink, the actual DSL line rate is always the lower rate.
                                    Note    The maximum peak cell rate is 8 kbps less than the line rate.
                                     
                                    Step 6interface atm interface-number


                                    Example:
                                    Router(config-ctrl)# interface atm0
                                     

                                    Enters ATM configuration mode for interface ATM 0.

                                     
                                    Step 7ip-address ip-address


                                    Example:
                                    Router(config-ctrl)# ip-address IP-address 
                                     

                                    Assigns an IP address to the DSL ATM interface.

                                     
                                    Step 8load-interval seconds


                                    Example:
                                    Router(config-ctrl)# load-interval 3
                                     

                                    Assigns a load interval value.

                                     
                                    Step 9no atm ilmi-keepalive [seconds]

                                    Example:
                                    Router(config-ctrl)# no atm ilmi-keepalive0
                                     

                                    Disables Integrated Local Management Interface (ILMI) keepalives.

                                    If you enable ILMI keepalives without specifying the number of seconds, the default time interval is 3 seconds.

                                     
                                    Step 10pvc [name] vpi/vci

                                    Example:
                                    Router(config-ctrl)# pvc 0/35
                                     

                                    Enters atm-virtual-circuit (interface-atm-vc) configuration mode, and configures a new ATM PVC by assigning a name (optional) and VPI/VCI numbers.

                                    The default traffic shaping is UBR; the default encapsulation is AAL5+LLC/SNAP.

                                     
                                    Step 11protocol protocol protocol-address broadcast


                                    Example:
                                    Router(config-ctrl)# protocol ip 10.10.10.2 broadcast
                                     

                                    Enables IP connectivity and creates a point-to-point IP address for the VC.

                                     
                                    Step 12encapsulation [encapsulation-type]

                                    Example:
                                    Router(config-ctrl)# encapsulation aal5snap
                                     

                                    Configures the ATM adaptation layer (AAL) and encapsulation type.

                                    • Use the aal2 keyword for AAL2
                                    • Use the aal5ciscoppp keyword for Cisco PPP over AAL5
                                    • Use the aal5mux keyword for AAL5+MUX
                                    • Use the aal5nlpid keyword for AAL5+NLPID
                                    • Use the aal5snap keyword for AAL5+LLC/SNAP (the default)

                                    Configuring the Cellular Wireless WAN Interface

                                    The Cisco 880 series and Cisco 810 series ISRs provide a third generation (3G) wireless interface for use over Global System for Mobile Communications (GSM) and code division multiple access (CDMA) networks. The interface is a 34-mm PCMCIA slot for Cisco 880 series.

                                    Its primary application is WAN connectivity as a backup data link for critical data applications. However, the 3G wireless interface can also function as the primary WAN connection for the router.

                                    To configure the 3G cellular wireless interface, follow these guidelines and procedures:

                                    Prerequisites for Configuring the 3G Wireless Interface

                                    The following are prerequisites to configuring the 3G wireless interface:

                                    • You must have wireless service from a carrier, and you must have network coverage where your router will be physically placed. For a complete list of supported carriers, see the data sheet at:

                                    http:/​/​www.cisco.com/​en/​US/​prod/​routers/​networking_​solutions_​products_​genericcontent0900aecd80601f7e.html

                                    • You must subscribe to a service plan with a wireless service provider and obtain a SIM card (GSM modem only) from the service provider.
                                    • You must check your LEDs for signal strength, as described in Table 1.
                                    • You should be familiar with the Cisco IOS software, beginning with Cisco NX-OS Release 4.1 or later. For Cisco 3G Wireless support, see the Cisco IOS documentation.
                                    • To configure your GSM data profile, you need the following information from your service provider:
                                      • Username
                                      • Password
                                      • Access point name (APN)
                                    • To configure your CDMA data profile for manual activation, you need the following information from your service provider:
                                      • Master Subsidy Lock (MSL) number
                                      • Mobile Directory number (MDN)
                                      • Mobile Station Identifier (MSID)
                                      • Electronic Serial Number (ESN)

                                    Restrictions for Configuring the Cellular Wireless Interface

                                    The following restrictions apply to configuring the Cisco 3G wireless interface:

                                    • A data connection can be originated only by the 3G wireless interface. Remote dial-in is not supported.
                                    • Because of the shared nature of wireless communications, the experienced throughput varies depending on the number of active users or the amount of congestion in a given network.
                                    • Cellular networks have higher latency than wired networks. Latency rates depend on the technology and carrier. Latency may be higher when there is network congestion.
                                    • VoIP is not currently supported.
                                    • Any restrictions that are part of the terms of service from your carrier also apply to the Cisco 3G wireless interface.
                                    • Cisco 880G ISR does not support online insertion and removal (OIR) of 3G modems. To replace a modem with another modem of the same type, use the Cisco CLI to enter the shutdown command on the cellular interface before you replace the modems. =
                                    • When a 3G modem is removed, the show interface cellular 0, show run, and show version command outputs still display cellular interface related information. The show interface command displays the following message, all other show commands have empty outputs.
                                    3G Modem not inserted
                                    
                                    • You can configure the cellular interface when the 3G modem is removed. However, the configuration is not effective until the 3G modem is inserted. The following message is shown when trying to configure the cellular interface while the modem is absent.

                                        Note


                                        When the cellular interface requires a static IP address, the address may be configured as ip address negotiated. Through IP Control Protocol (IPCP), the network ensures that the correct static IP address is allocated to the device. If a tunnel interface is configured with the ip address unnumbered cellular interface command, the actual static IP address must be configured under the cellular interface, in place of ip address negotiated. For a sample cellular interface configuration, see the Basic Cellular Interface Configuration.

                                          Configuring Data Dedicated Transmission Mode (DDTM)

                                          On CDMA modems, data transmission is disrupted by incoming voice calls if data dedicated transmission mode (DDTM) is disabled. You can enable DDTM mode so the modem ignores incoming voice calls.

                                          To enable DDTM on a CDMA modem, use the cdma ddtm command in configuration mode.

                                          This command is enabled by default. You can disable this feature by using the no cdma ddtm command.


                                          Note


                                          When DDTM is enabled, only voice calls are blocked for the MC5728v modems. On the AC597E and MC5725 and MC 5727, incoming SMS messages are also blocked.

                                          Configuring Dual SIM for Cellular Networks on Cisco 819 Series ISR

                                          The Dual SIM feature implements auto-switch and failover between two cellular networks on a Cisco 819 ISR. This feature is enabled by default with SIM slot 0 being the primary slot and slot 1 being the secondary (failover) slot.


                                          Note


                                          For instructions on how to configure the Dual SIM feature for 4G LTE cellular networks, see the Cisco 4G LTE Software Installation Guide .

                                          You can configure the Dual SIM feature using the following commands:

                                          Command

                                          Syntax

                                          Description

                                          gsm failovertimer

                                          gsm failovertimer <1-7> 

                                          Sets the failover timer in minutes.

                                          gsm sim authenticate

                                          gsm sim authenticate <0,7> <pin> slot <0-1> 

                                          Verifies the SIM CHV1 code.

                                          gsm sim max-retry

                                          gsm sim max-retry <0-65535>

                                          Specifies the maximum number of failover retries. The default value is 10.

                                          gsm sim primary slot

                                          gsm sim primary slot <0-1>

                                          Modifies the primary slot assignment.

                                          gsm sim profile

                                          gsm sim profile <1-16> slot <0-1>

                                          Configures the SIM profile.

                                          Note the following:

                                          • For auto-switch and failover to work, configure the SIM profile for slots 0 and 1 using the gsm sim profile command.
                                          • For auto-switch and failover to work, configure the chat script without a specific profile number.
                                          • If no SIM profile is configured, profile #1 is used by default.
                                          • If no GSM failover timer is configured, the default failover timeout is 2 minutes.
                                          • If no GSM SIM primary slot is configured, the default primary SIM is slot 0.

                                          The following example shows you how to set the SIM switchover timeout period to 3 minutes:

                                          router(config-controller)# gsm failovertimer 3
                                          

                                          The following example shows you how to authenticate using an unencrypted pin:

                                          router(config-controller)# gsm sim authenticate 0 1234 slot 0

                                          The following example shows you how to set the maximum number of SIM switchover retries to 20:

                                          router(config-controller)# gsm sim max-retry 20

                                          The following example shows you how to set SIM slot 1 as the primary slot:

                                          router(config-controller)# gsm sim primary slot 1
                                          

                                          The following example shows you how to configure the SIM card in slot 0 to use profile 10:

                                          router(config-controller)# gsm sim profile 10 slot 0
                                          

                                          Perform the following commands to manually switch the SIM:

                                          Command

                                          Configuring Router for Image and Config Recovery Using Push Button for Cisco 819 Series ISR Router

                                          A push button feature is available on the Cisco 819 ISR. The reset button on the front panel of the router enables this feature.

                                          Perform the following steps to use this feature:

                                          SUMMARY STEPS

                                            1.    Unplug power.

                                            2.    Press the reset button on the front panel of the router.

                                            3.    Power up the sytem while holding down the reset button.


                                          DETAILED STEPS
                                            Step 1   Unplug power.
                                            Step 2   Press the reset button on the front panel of the router.
                                            Step 3   Power up the sytem while holding down the reset button.

                                            The system LED blinks four times indicating that the router has accepted the button push.


                                            What to Do Next

                                            Using this button takes effect only during ROMMON initialization. During a warm reboot, pressing this button has no impact on performance. Table 1 shows the high level functionality when the button is pushed during ROMMON initialization.

                                            ROMMON Behavior

                                            IOS Behavior

                                            • Boots using default baud rate.
                                            • Performs auto-boot.
                                            • Loads the *.default image if available on compact flash
                                            Note    If no *.default image is available, the ROMMON will boot up with the first Cisco IOS image on flash.

                                            Examples of names for default images:

                                            c800-universalk9-mz.SPA.default,

                                            c-800-universalk9_npe-mz.151T.default,

                                            image.default

                                            Note    You can only have one configuration file with *.cfg option. Having more than one file will result in uncertain operational behavior.

                                            If the configuration named *.cfg is available in nvram storage or flash storage, IOS will perform a backup of the original configuration and will boot up using this configuration.

                                            Note    You can only have one configuration file with *.cfg option. Having more than one file will result in uncertain operational behavior.

                                            Use the show platform command to display the current bootup mode for the router. The following sections show sample outputs when the button is not pushed and when the button is pushed.

                                            Output When Button Is Not Pushed: Example

                                            Push Button in WLAN AP

                                            When the push button on the front panel is pressed, WLAN AP will perform both image and configuration recovery.

                                            To perform image recovery, WLAN will go into the boot loader so that the user can download the image from the bootloader prompt.

                                            To perform configuration recovery, WLAN AP will overwrite the contents of flash:/config.txt with the contents of flash:/cpconfig-ap802.cfg file if available in flash drive. Otherwise, flash:/config.txt will be deleted.

                                            Configuring WAN Mode on Cisco 860VAE ISRs

                                            The Cisco 866VAE, Cisco 867VAE, Cisco 866VAE-K9, and Cisco 867VAE-K9 routers can be configured to use either a GE interface or a DSL interface as a WAN link. DSL is the default WAN interface when the Cisco 866VAE, Cisco 867VAE, Cisco 866VAE-K9, and Cisco 867VAE-K9 routers boot.

                                            After the router boots up, the desired WAN interface can be selected using the wan mode command. When WAN mode is configured as Ethernet, both ATM0 and Ethernet0 interfaces will be forced into shutdown state. Entering the no shutdown command on either of the DSL interfaces will be rejected with a message WAN interface is Ethernet . Similarly, when the WAN mode is DSL, the GE WAN interface will be put in shutdown state and the no shutdown command will be rejected with the message WAN interface is DSL .


                                            Note


                                            The routers do not support enabling both GE and DSL interfaces simultaneously.

                                            Use the wan mode dsl | ethernet command to switch from DSL to Ethernet interfaces or vice versa.

                                              Exits configuration mode and returns to it would take the router back to privileged EXEC mode.

                                               
                                              Displaying WAN Mode Configuration

                                              Use the show running-config command to view the initial configuration, as shown in the following example for a Cisco 866VAE router.


                                              Note


                                              Your Cisco router displays the WAN mode during the boot sequence after the initial configuration is complete.

                                              Configuring the Fast Ethernet LAN Interfaces

                                              The Fast Ethernet LAN interfaces on your router are automatically configured as part of the default VLAN and are not configured with individual addresses. Access is provided through the VLAN. You can also assign the interfaces to other VLANs. For more information about creating VLANs, see Configuring Ethernet Switches

                                              Configuring the Wireless LAN Interface

                                              The Cisco 860, Cisco 880, and Cisco 890 series wireless routers have an integrated 802.11n module for wireless LAN connectivity. The router can then act as an access point in the local infrastructure. For more information about configuring a wireless connection, see Chapter 11, “Basic Wireless Device Configuration.”

                                              Configuring a Loopback Interface

                                              The loopback interface acts as a placeholder for the static IP address and provides default routing information.

                                              Perform these steps to configure a loopback interface, beginning in global configuration mode:

                                                Exits configuration mode for the loopback interface and returns to global configuration mode.

                                                 

                                                Configuration Example: Configuring a Loopback Interface

                                                The loopback interface in this sample configuration is used to support Network Address Translation (NAT) on the virtual-template interface. This configuration example shows the loopback interface configured on the Fast Ethernet interface with an IP address of 200.200.100.1/24, which acts as a static IP address. The loopback interface points back to virtual-template1, which has a negotiated IP address.

                                                !
                                                interface loopback 0
                                                ip address 200.200.100.1 255.255.255.0 (static IP address)
                                                ip nat outside
                                                !
                                                interface Virtual-Template1
                                                ip unnumbered loopback0
                                                no ip directed-broadcast
                                                ip nat outside
                                                !
                                                

                                                Verifying Configuration

                                                To verify that you have properly configured the loopback interface, enter the show interface loopback command. You should see verification output similar to the following example.

                                                Router# show interface loopback 0

                                                Another way to verify the loopback interface is to ping it:

                                                Router# ping 200.200.100.1 
                                                Type escape sequence to abort.
                                                Sending 5, 100-byte ICMP Echos to 200.200.100.1, timeout is 2 seconds:
                                                !!!!!
                                                Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms
                                                

                                                Configuring Static Routes

                                                Static routes provide fixed routing paths through the network. They are manually configured on the router. If the network topology changes, the static route must be updated with a new route. Static routes are private routes unless they are redistributed by a routing protocol.

                                                Follow these steps to configure static routes, beginning in global configuration mode.

                                                  What to Do Next

                                                  For general information on static routing, see the “Concepts” section on page B-1

                                                  Example

                                                  In the following configuration example, the static route sends out all IP packets with a destination IP address of 192.168.1.0 and a subnet mask of 255.255.255.0 on the Fast Ethernet interface to another device with an IP address of 10.10.10.2. Specifically, the packets are sent to the configured PVC.

                                                  You do not need to enter the command marked “(default).” This command appears automatically in the configuration file generated when you use the show running-config command.

                                                  !
                                                  ip classless (default)
                                                  ip route 192.168.1.0 255.255.255.0 10.10.10.2!
                                                  

                                                  Verifying Static Routing Configuration

                                                  To verify that you have properly configured static routing, enter the show ip route command and look for static routes signified by the “S.”

                                                  You should see verification output similar to the following:

                                                  Configuring Dynamic Routes

                                                  In dynamic routing, the network protocol adjusts the path automatically, based on network traffic or topology. Changes in dynamic routes are shared with other routers in the network.

                                                  The Cisco routers can use IP routing protocols, such as Routing Information Protocol (RIP) or Enhanced Interior Gateway Routing Protocol (EIGRP), to learn routes dynamically. You can configure either of these routing protocols on your router.

                                                  Configuring Routing Information Protocol

                                                  To configure the RIP routing protocol on the router, perform these steps, beginning in global configuration mode:

                                                      For general information on EIGRP concepts, see the “Enhanced IGRP” section on page B-3

                                                      Example Configuration: EIGRP

                                                      The following configuration example shows the EIGRP routing protocol enabled in IP networks 192.145.1.0 and 10.10.12.115. The EIGRP autonomous system number is 109.

                                                      To see this configuration, use the show running-config command, beginning in privileged EXEC mode.
