•Feature Information for RIPv2: RFC 1724 MIB Extensions

Prerequisites for RIPv2 Monitoring with SNMP Using the RFC 1724 MIB Extensions

•RIPv2 must be configured on the router.

•Your SNMP Network Management Station (NMS) must have the RFC 1724 RIPv2 MIB installed.

•Your SNMP NMS must have the following MIBs installed because RFC 1724 imports data types and object Identifiers (OIDs) from them:

–SNMPv2-SMI

–SNMPv2-TC

–SNMPv2-CONF

–RFC1213-MIB

Restrictions for RIPv2 Monitoring with SNMP Using the RFC 1724 MIB Extensions

This implementation of the RIPv2 MIB does not track any data associated with a RIP Virtual Routing and Forwarding (VRF) instance. Only interfaces that are assigned IP addresses in the IP address space configured by the network network-address command in RIP router configuration mode are tracked. Global data is tracked only for changes to the main routing table.

Information About RIPv2 Monitoring with SNMP Using the RFC 1724 MIB Extensions

The following sections contain information about MIB objects standardized as part of RFC 1724, and benefits of the RFC 1724 MIB.

•RIPv2 MIB

•Benefits of the RIPv2 MIB

RIPv2 MIB

This section describes the MIB objects that are provided by RFC 1724 definitions. The RIPv2 MIB consists of the following managed objects:

•Global counters—Used to keep track of changing routes or neighbor changes.

•Interface status table—Defines objects that are used to keep track of statistics specific to interfaces.

•Interface configuration table—Defines objects that are used to keep track of interface configuration statistics.

•Peer table—Defined to monitor neighbor relationships. This object is not implemented in Cisco IOS Software.

Table 1, Table 2, and Table 3 show the objects that are provided by RFC 1724 RIPv2 MIB definitions. The objects are listed in the order in which they appear within the RFC 1724 RIPv2 MIB, per the tables that describe them. The statistics for all of the objects in the global counters can be obtained by querying the rip2Globals object identifier (OID) using snmpwalk, or a similar SNMP toolset command on your NMS.

Table 1 shows the RFC 1724 RIPv2 MIB global counter objects.

Table 1 RFC 1724 RIPv2 MIB Global Counters Objects

Global Counter

Object

Description

rip2Globals

rip2GlobalRouteChanges

Number of route changes made to the IP route database by RIP. Number is incremented when a route is modified.

rip2GlobalQueries

Number of responses sent to RIP queries from other systems. Number is incremented when RIP responds to a query from another system.

The objects in the RFC 1724 RIPv2 MIB interface table track information on a per interface basis. All object in the RFC 1724 RIPv2 MIB interface table, except for the rip2IfStatAddress object, represent newly tracked data within RIP. There are no equivalent show commands for these objects. All objects in the RIPv2 MIB interface table are implemented read-only.

Table 2 shows the RFC 1724 RIPv2 MIB interface table objects. The statistics for all objects in the interface table can be obtained by querying the sequence name Rip2IfStatEntry using snmpwalk or a similar SNMP toolset command on your NMS.

Table 2 RFC 1724 RIPv2 MIB Interface Table Objects

Sequence Name

Object

Description

Rip2IfStatEntry

rip2IfStatAddress

The IP address of this system on the indicated subnet. For unnumbered interfaces, the value of 0.0.0.N, where the least significant 24 bits (N) are the ifIndex for the IP interface in network byte order.

rip2IfStatRcvBadPackets

The number of RIP response packets received by the RIP process that were subsequently discarded for any reason. For example, a version 0 packet or an unknown command type.

rip2IfStatRcvBadRoutes

The number of routes, in valid RIP packets, that were ignored for any reason. This is incremented when:

•The address family identifier does not equal AF_INET.

•If a RIP v2 update is received and the class D and greater.

•If a RIP v2 update is received and the address is a martian address.

rip2IfStatSentUpdates

The number of triggered RIP updates actually sent on this interface. This explicitly does not include full updates sent containing new information.

rip2IfStatStatus

This value is always set to 1.

The objects in the RFC 1724 RIPv2 MIB interface configuration table track information on a per interface basis. Except for the Rip2IfConfAuthType object, the data for the objects in the RFC 1724 RIPv2 MIB interface configuration table can also be gathered with the show ip protocol commands. All objects in the RIPv2 MIB interface table are implemented read-only.

Table 3 shows the RIPv2 MIB interface configuration table objects. The statistics for all objects in the configuration table can be obtained by querying the sequence name rip2IfConfEntry using snmpwalk or a similar SNMP toolset command on your NMS.

Table 3 RFC 1724 RIPv2 MIB Interface Configuration Table Object Types

Sequence Name

Object Type

Description

rip2IfConfEntry

rip2IfConfAddress

The IP address of this system on the indicated subnet. For unnumbered interfaces, the value 0.0.0.N, where the least significant 24 bits (N) are the ifIndex for the IP interface in network byte order.

rip2IfConfDomain

This value is always equal to "".

rip2IfConfAuthType

The type of authentication used on this interface.

rip2IfConfAuthKey

The value to be used as the authentication key whenever the corresponding instance of rip2IfConfAuthType has a value other than no authentication.

rip2IfConfSend

The version of RIP updates that are sent on this interface.

rip2IfConfReceive

The version of RIP updates that are accepted on this interface.

rip2IfConfDefaultMetric

This variable indicates the metric that is used for the default route entry in RIP updates originated on this interface.

rip2IfConfStatus

This value is always set to 1.

rip2IfConfSrcAddress

The IP address that this system will use as a source address on this interface. If it is a numbered interface, this must be the same value as rip2IfConfAddress. On unnumbered interfaces, it must be the value of rip2IfConfAddress for some interface on the system.

Benefits of the RIPv2 MIB

The RFC 1724 RIPv2 MIB extensions allow network managers to monitor the RIPv2 routing protocol using SNMP through the addition of new global counters and table objects that previously were not supported by the RFC 1389 RIPv2 MIB. The new global counters and table objects are intended to facilitate quickly changing routes or failing neighbors.

How to Enable RIPv2 Monitoring with SNMP Using the RIPv2: RFC124 MIB Extensions

This section contains the following tasks:

•Enabling SNMP Read-Only Access on the Router (required)

•Verifying the Status of the RIPv2: RFC124 MIB Extensions on the Router and Your Network Management Station (optional)

Enabling SNMP Read-Only Access on the Router

There are no router configuration tasks required for the RIPv2: RFC124 MIB Extensions feature itself. SNMP read-only access to the objects in the RFC 1724 RIPv2 MIB is enabled when you configure the SNMP server read-only community string on the router.

Note When you configure an SNMP server read-only community string on the router, you are granting SNMP read-only access to the objects that support read-only access in all MIBs that are available in the version of Cisco IOS that is running on the router.

Perform this task to configure the SNMP server read-only community string on the router to enable SNMP read-only access to MIB objects (including the RFC 1724 RIPv2 MIB extensions) on the router.

SNMP Community Strings

Routers can have multiple read-only SNMP community strings. When you configure an SNMP read-only community string for the snmp-server command on the router, an existing SNMP snmp-server read-only community string is not overwritten. For example, if you enter the snmp-server community string1 ro and snmp-server community string2 ro commands on the router, the router will have two valid read-only community strings—string1 and string2. If this is not the behavior that you desire, use the no snmp-server community string ro command to remove an existing SNMP read-only community string.

Timesaver If you already have an SNMP read-only community string configured on your router you do not need to perform this task. After you load Cisco IOS Release 12.4(6)T or a later release on your router, you can use SNMP commands on your NMS to query the RFC 1724 RIPv2 MIB on your router.

SUMMARY STEPS

1. enable

2. configure terminal

3. snmp-server community string1 ro

4. end

DETAILED STEPS

Command or Action

Purpose

Step 1

enable
Example:

Router> enable

Enables privileged EXEC mode.

•Enter your password if prompted.

Step 2

configure terminal
Example:

Router# configure terminal

Enters global configuration mode.

Step 3

snmp-server community string1 ro
Example:

Router(config)# snmp-server community T8vCx3 ro

Enables SNMP read-only access to the objects in the MIBs that are included in the version of Cisco IOS software that is running on the router.

Note For security purposes, do not use the standard default value of public for your read-only community string. Use a combination of uppercase and lowercase letters and numbers for the password.

Step 4

end
Example:

Router(config)# end

Ends your configuration session and returns to privileged EXEC mode.

Verifying the Status of the RIPv2: RFC124 MIB Extensions on the Router and Your Network Management Station

Perform this optional task on your NMS to verify the status of the RFC 1724 RIPv2 MIB extensions on the router and on your NMS.

Note This task uses the NET-SNMP toolset that is available in the public domain. The step that is documented uses a terminal session on an NMS that is running Linux. Substitute the SNMP command from the SNMP toolset on your NMS as appropriate when you perform this task.

Prerequisites

Your NMS must have the RFC 1724 MIB installed.

SUMMARY STEPS

1. snmpwalk -m all -v2c ip-address -c read-only-community-string rip2Globals

DETAILED STEPS

Step 1 snmpwalk -m all -v2c ip-address -c read-only-community-string rip2Globals

Use the snmpwalk command for the rip2Globals object in the RFC 1724 RIPv2 MIB to display the data for the objects associated with this object. This step verifies that the NMS is configured to send queries for objects in the RFC 1724 RIPv2 MIB and that the router is configured to respond to the queries.
