Troubleshooting RIP Routes Advertisement

All the problems discussed so far deal with the problem on the receiving end or the problem in the middle (Layer 2).

A third possible cause exists when routes are not being installed in the routing table. The sender could be having a problem sending RIP updates for some reason. As a result, the receiver cannot install the RIP routes in the routing table. This section talks about the things that can go wrong on the sender's side.

This section discusses some of the possible scenarios that can prevent RIP routes from being advertised. Some cases overlap with router installation problems ‚ for example, missing network statement(s) or an interface that is down. This section assumes that, after troubleshooting the problems previously addressed in the "Troubleshooting RIP Routes Installation" section, the problems persist. This section presents recommendations on where to go next to resolve those issues.

Two of the most prevalent problems that can go wrong on the sender's end deal with RIP route advertisement:

• The sender is not advertising RIP routes.

• Subnetted routes are missing.
