Cisco commands to verify OSPF
The following commands are in addition to the Cisco commands used for RIP (see
Example 7-39):
sh ip ospf neighbor Lists the OSPF neighbors of the current switch.
sh ip ospf database Provides a dump of the OSPF topology database, which includes
all switches in the same area as the one where the command is
issued.
Example 7-39 Cisco commands to verify OSPF
sh ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route
