Troubleshooting RIP
No RIP updates received
Symptom
No RIP updates are received when the links work correctly.
Analysis
After enabling RIP, 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
• Use the display current-configuration command to verify RIP configuration.
• Use the display rip command to verify that an interface is disabled.
Route oscillation occurred
Symptom
When all links work correctly, 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.
