Troubleshooting Redistribution Problems in OSPF

This section describes problems related to redistribution in OSPF. When a router in OSPF does the redistribution, it becomes an ASBR. The routes that are redistributed into OSPF could be directly connected routes, static routes, or dynamically learned routes from another routing protocol or another OSPF process.

The following are problems that can happen during redistribution:

• ASBR is not advertising redistributed routes.

• OSPF is not installing external routes in the routing table.

The second problem already was discussed in the earlier section on OSPF routes installation problems. The first problem is discussed in the section that follows .
