Verifying the OSPF configuration for R2

The following example shows the output of the show ip route command for R2. The output shows that routes to 10.0.0.1/32, 10.0.0.3/32, 10.0.20.0/24, 10.0.30.0/24, and 10.0.60.0/24, which have been learned through OSPF processes 4 and 5, are present in the routing table and are the selected routes that are copied to the FIB. The 10.0.0.2/32, 10.0.40.0/24, and 10.0.50.0/24 networks are directly connected to R2. Directly connected routes have a preference over OSPF-discovered routes.

The following example shows the output of the show ip ospf neighbor command. The output shows that there are no OSPF neighbors in the default process (process 0).

vyatta@R2:~$ show ip ospf neighbor
Total number of full neighbors: 0
OSPF process 0 routing-instance(default):
Neighbor ID     Pri   State            Dead Time   Address         Interface

The following example shows the output of the show ip ospf process 4 neighbor command. The output shows that there is only one OSPF neighbor for OSPF process 4.

vyatta@R2:~$ show ip ospf process 4 neighbor
Total number of full neighbors: 1
OSPF process 4 routing-instance(default):

The following example shows the output of the show ip ospf process 5 neighbor command. The output shows that there is only one OSPF neighbor for the configured OSPF process 5.

vyatta@R2:~$ show ip ospf process 5 neighbor
Total number of full neighbors: 1
OSPF process 5 routing-instance(default):
Neighbor ID     Pri   State            Dead Time   Address         Interface

The following example shows the output of the show ip route ospf command. The output shows the OSPF routes in the routing table.
