Verify That OSPF Neighbors Are Established

Purpose

After configuring OSPF, you must verify that neighboring routers have formed adjacencies with each other.

Action

To verify OSPF neighbors, enter the following Junos OS CLI operational mode command:

user@host> show ospf neighbor

Sample Output

user@R1> show ospf neighbor

Meaning

The sample output from the ingress, transit, and egress routers shows that all routers in the network shown in MPLS Network Topology have formed OSPF neighbor adjacencies.
