Troubleshooting IGRP Redistribution Problems

This section covers a common problem that can happen during redistribution in IGRP. Redistribution occurs when another routing protocol, static route, or connected route is being injected into IGRP. Special care is required during this process to avoid any routing loops . Metrics also should be defined during this process, to avoid problems.

The most prevalent problem encountered with IGRP redistribution is that redistributed routes are not getting installed in the routing table of the IGRP routers receiving these routes. When destination routes are not present in the routing table, no data can reach those destinations.
