The same verification commands used to verify single-area OSPF also can be used to verify the multiarea OSPF topology in the figure:
- show ip ospf neighbor
- show ip ospf
- show ip ospf interface
Commands that verify specific multiarea information include:
- show ip protocols
- show ip ospf interface brief
- show ip route ospf
- show ip ospf database
Note: For the equivalent OSPFv3 command, simply substitute ip with ipv6.
