Troubleshooting
Step 1 |
Verify that the routes have been assigned the proper tags by using the command show ip ospf database external or the command show ip route ip-address mask. |
Step 2 |
Verify that the redistribute command is referencing the correct routing process and process number (if applicable). |
Step 3 |
Verify that the redistribute command is referencing the correct route map name. |
Step 4 |
Verify the syntax and logic of the route map. |
To avoid problems associated with mutual redistribution, use a distribute list (see Sections 7-5, 7-10, and 7-15) or a route map to allow only routes that have originated in the routing process domain. For example, if EIGRP is redistributed into OSPF and OSPF is redistributed into EIGRP on the same router, then OSPF routes will be redistributed back into OSPF from EIGRP and EIGRP routes will be redistributed back into EIGRP from OSPF. Using a route map or distribute list will prevent this from occurring.
