RIP Troubleshooting
1.
Wrong network command(s): the network command is used to tell RIP what networks to advertise, but also
where to send RIP routing updates. Wrong or missing network commands will cause issues.
2.
Interface shut: A network on an interface that is in shutdown will not be advertised.
3.
Passive interface: An interface that is configured as passive will not send any RIP updates.
4.
Version mismatch: RIP has two versions; both routers must use the same version.
5.
Max hop count: When the hop count is 16, the network is considered unreachable. If the network is small,
check for offset-lists that increase the metric.
6.
Route Filtering: Filters might prevent RIP updates from being sent or received.
7.
Authentication: Both RIP routers must have the same authentication parameters.
8.
Split horizon: Networks that are learned on an interface are not advertised out of the same interface.
