Verifying OSPF and VRRP Configuration Status

Verify the OSPF (Open Shortest Path First) neighbor adjacencies are established and that the DR and BDR status is correct.

Verify that the VRRP (Virtual Router Redundancy Protocol) virtual router (VR) is running and the VRRP master/backup status is correct.

OSPF and VRRP verification example:
