Route oscillation occurred
Symptom
When all links work well, route oscillation occurs on the RIP network. After displaying the routing table,
you might find some routes appear and disappear in the routing table intermittently.
Analysis
In the RIP network, make sure all the same timers within the entire network are identical and relationships
between timers are reasonable. For example, the timeout timer value should 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.
