Introduction
This chapter provides troubleshooting solutions to some common Routing
Information Protocol (RIP) problems:
• Handling Routing Table Problems
• Handling RIP Version Inconsistencies
Handling Routing Table Problems
Problems that occur when hosts on one network cannot access hosts on another
network may occur on an internetwork running only RIP.
The following sections provide instructions for resolving RIP routing table problems:
• Misconfigured or Missing Network Router Table Entries
• Misconfigured Route Filtering
• Split Horizon is Disabled
Misconfigured or Missing Network Router Table Entries
Follow these steps to resolve routes that are missing from the routing table:
1. To view the router configuration, use the show running-config command in
Privileged EXEC mode.
2. Ensure that a network command is specified in Router Configuration mode for
every network to which a router interface belongs.
For example, enter the following commands to enable RIP on the interfaces:
RDN(config)#router rip
RDN(config-rip)#network 10.10.10.3 255.255.255.0
RDN(config-rip)#network 10.10.20.3 255.255.255.0
3. Ensure the correct process IDs, addresses, and other variables are properly
specified for the RIP routing protocol.
