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 must be configured on the local end. Solution 1. Use the display current-configuration command to verify RIP configuration. 2. Use the display rip command to verify whether an interface is disabled. Route oscillation occurred Symptom When all links function, route oscillation occurs on the RIP network. After displaying the routing table, you may find some routes intermittently appear and disappear in the routing table. Analysis In the RIP network, make sure that all the same timers within the entire network are identical and have logical relationships between them. For example, the timeout timer value must be greater than the update timer value. Solution 1. Use the display rip command to verify the configuration of RIP timers. 2. Use the timers command to adjust timers properly. 47
