Verify the OSPF Protocol Configuration

 

Purpose

After you have checked interfaces and neighbors, verify the OSPF protocol configuration.

Action

To verify the OSPF protocol configuration, enter the following command from the ingress, transit, and egress routers:

Sample Output 1

Sample Output 2

Sample Output 3

Meaning

All three sample outputs show that the loopback interface is not included on any of the routers. Including the loopback (lo0) interface is important when you have the RID manually configured.

In addition, Sample Output 2 from transit router R3 shows that traffic engineering is not configured. Traffic engineering must be manually enabled when you configure OSPF for an MPLS network.

Because the loopback interface and traffic engineering are missing from the OSPF protocol configuration, the LSP does not work as expected.
