2.7 Troubleshooting RIP
2.7.1 No RIP Updates Received
Symptom:
No RIP updates are received when the links work well.
Analysis:
After enabling RIP, you must use the
network
command to enable corresponding
interfaces. Make sure no interfaces are disabled from handling RIP messages.
If the peer is configured to send multicast messages, the same should be configured on
the local end.
Solution:
z
Use the
display current-configuration
command to check RIP configuration
z
Use the
display rip
command to check whether some interface is disabled
2.7.2 Route Oscillation Occurred
Symptom:
When all links work well, route oscillation occurs on the RIP network. After displaying
the routing table, you may find some routes appear and disappear in the routing table
intermittently.
Analysis:
In the RIP network, make sure all the same timers within the whole network are
identical and relationships between timers are reasonable. For example, the timeout
timer value should be larger than the update timer value.
Solution:
z
Use the
display rip
command to check the configuration of RIP timers
z
Use the
timers
command to adjust timers properly.
