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.
