| >set systemname HQ | Configures a system name for the router - this name will be used during PPP negotiation
with the other router| HQ>set ppp secret client | prompts for chap password | Enter Password: happy | ReEnter Password: happy | Password will be sent when challenged from the destination router
| HQ>set encapsulation ppp | Enables ppp encapsulation for the router | HQ>set ppp authentication incoming chap | Configures PPP authentication based on incoming calls only. The "Incoming" is a
system parameter and can not be set on a per-profile basis.
| HQ>cd lan | Changes directory in order to configure the LAN profile | HQ:LAN>set bridging off | Disables bridging in the LAN profile | HQ:LAN>set ip routing on | Enables ip routing in the LAN profile | HQ:LAN>set ip 198.52.110.254 | Configures the ip address for the LAN profile - or can be thought of as setting
the ip address for the LAN interface | HQ:LAN>set subnet 255.255.255.0 | Configures the ip subnet mask for the LAN profile ip address
| HQ>set user remote | Creates a user profile in order to configure parameters for outgoing/incoming
calls - may also be refered to as the WAN interface for which the 750 series
may have multiple virtual (accomplished by the use of different profiles) for
the same physical interface
| HQ:remote>set bridging off | Disables bridging at the user profile | HQ:remote>set ip routing on | Enables ip routing at the user profile |
HQ:remote>set ip route destination 198.52.211.0/24 gateway 192.168.1.2 | Static routing statement for a hidden or otherwise known as a private Internet
network (per rfc 1918). Private networks will not be propagated on the internet
hence the use of static routes is required for these conncections.
The command is used at the profile level:
Set ip route destination (network number of the ip network on the BRI interface
of the destination router)
/24 (the number of bits in the subnet mask for the destination network)
gateway (address of the BRI interface on the destination router, which in this
case is a private internet network) | HQ:remote>set ip propagate off | Determines whether or not the route resulting from this interface will be
propagated in RIP broadcasts. This is a profile-based command.
| HQ:remote>set ip 192.168.1.1 | Configures the ip address of this particular profile. Will be associated with a
connection when there is traffic associated with this network.
| HQ:remote>set ip netmask 255.255.255.0 | Configures ip subnet mask for the profiles IP address | HQ:remote>set ip framing none | Configures the encapsulation that IP packets will take. It only applies when
IP routing is enabled. Note: Use "None" to set the packet framing to Internet Protocol Control Protocol (IPCP). Choosing IPCP sets the framing to be used when connectinng to another router/IP host using PPP. Use "Ethernet_II" when connecting to another router
using CPP (2060 series, 750, 760 series) Default is "Ether"
| HQ:remote>set timeout 120 | Configures the amount of time in seconds before the ISDN line will be disconnected if
there is no Ethernet activity.
| HQ:remote>set 1 number 14085224567 | Configures the channel 1 phone number to be called when this profile is initiated
| HQ:remote>set 2 number 14085224567 | Configures the channel 2 phone number to be called when this profile is initiated
| HQ:remote>set ppp secret host (prompts for chap password) | prompts for chap password | Enter Password: happy | ReEnter Password: happy | ReEnter Password: happy | Password will be sent when challenged from the destination router | HQ:remote>set ppp authentication outgoing chap | Configures PPP authentication based on outgoing calls only. It determines if any and
what type of authentication is negotiated by LCP to authenticate the remote unit when
using PPP. The "Outgoing" option is a profile parameter only.

| hostname remote | Configures router name which will be used for negotiation purposes when PPP
authentication is enabled. The name of this router is "remote". When configuring
PPP authentication the destination router must have a username of "remote" (this is
case sensitive so it must match exactly) and the same is true in terms of this router
it needs the user name and password of the remote router (see below for further
description)| username HQ password happy | The username "HQ" is the hostname of the destination router and is referenced
in the dialer map command for authentication purposes. The username is case
sensitive and must match the destination router's hostname exactly.
The password happy is used as the ppp authentication password for the user HQ. | interface ethernet 0 | Shows the interface and its configuration (in this example it is only a header).
This is also a command that changes the current location into the interface defined,
which in this case is ethernet 0. After changing into an interface, you may enter
all needed config commands. | ip address 198.52.211.254 255.255.255.0 | Configures the ip address and subnet mask for interface E0 or ethernet 0
| interface bri 0 | Shows the interface and its configuration (in this example it is only a header).
This is also the command that changes the current location into the interface defined,
which in this case is bri 0. After changing into an interface, you may enter all
needed config commands. | ip address 192.168.1.2 255..255.255.0 | Configures the ip address and subnet mask for interface bri0 or basic rate
interface 0. | encapsulation ppp | Enables ppp encapsulation in order to negotiate ppp
| dialer idle-timeout 300 | This command specifies the idle number in seconds. This is the time the connection
will remain open if no interesting traffic is being routed across this link. The
timer is reset each time an interesting packet is forwarded across the ISDN connection.
The idle-timeout should be set to the same value on both routers. In this example,
the line will drop after 5 consecutive minutes without interesting traffic. | dialer map ip 192.168.1.1 name HQ broadcast 14085221234 | Dialer map command uses the name of the destination router to authenticate the
dialed router and if authentication is successful will map the bri 0 interface to
the destination router. It will use the phone number at the end of the map statement
to start the call. Again the name of the destination router in this case "HQ" is case
sensitive and must match the actual name of the destination router.
Broadcast enables broadcast packets to be forwarded to this address. (i.e. IP, RIP or
IGRP updates)
To use multilink ppp which enables the use of both B channels for traffic you must
enter a second dialer map with the second phone of the destination routers 2nd B channel. | dialer-group 1 | The dialer-group 1 command associates this interface with the dialer-list 1 definition
(explained later in this description). The interface will now consider anything defined
in dialer-list 1 as interesting traffic and initiate a call if there is not a connection
already. | ppp authentication chap | Enables ppp authentication via chap (Challenge Handshake Authentication Protocol)
| ppp multilink | Enables ppp multilink which allows the use of both B channels for traffic.
| ip route 198.52.110.0 255.255.255.0 192.168.1.1 | Creates a static route to the network 198.52.110.0. This is a global command
entered at the "router name(config)#" prompt and is not valid at the interface prompt. | dialer-list 1 protocol ip permit | This command defines a dialer list to control dialing by protocol or by a combination of
protocol and access list. This is a global command entered at the "router name(config)#"
prompt | |
