Troubleshooting RIP
No RIP updates received
Symptom
No RIP updates are received when the links work properly.
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
1. Use the display current-configuration command to check RIP configuration
2. Use the display rip command to check whether an interface is disabled
Route oscillation occurred
Symptom
When all links work properly, route oscillation occurs on the RIP network. After displaying the routing
table, you might find some routes intermittently appear and disappear in the routing table.
