Troubleshooting OSPF Routing Tables
After you have veri?¬?ed that the adjacencies are correct, the next step is to troubleshoot/verify the
routing tables. Figure 4-10 shows the procedures for verifying the routing tables.
Figure 4-10 Troubleshooting OSPF Routing Tables
An OSPF route found in the routing table can have a variety of different codes:
?– O: OSPF intra-area, within the same area, route from a router within the same OSPF area
?– O IA: OSPF inter-area, from another area in the OSPF network, route from a router in a
different OSPF area
?– O E1 or E2: An external OSPF route from another autonomous system
If you have a single OSPF area, you should not see O IA routes in the routing table.
