OSPF Example

This example configuration implements an OSPF setup using the required information from Example OSPF Configuration.

tnsr(config)# route dynamic ospf
tnsr(config-frr-ospf)# server vrf default
tnsr(config-ospf)# ospf router-id 10.2.0.1
tnsr(config-ospf)# passive-interface GigabitEthernet3/0/0
tnsr(config-ospf)# exit
tnsr(config-frr-ospf)# interface GigabitEthernet3/0/0
tnsr(config-ospf-if)# ip address * area 0.0.0.0
tnsr(config-ospf-if)# exit
tnsr(config-frr-ospf)# interface TenGigabitEthernet6/0/0
tnsr(config-ospf-if)# ip address * cost 5
tnsr(config-ospf-if)# ip address * area 0.0.0.0
tnsr(config-ospf-if)# exit
tnsr(config-frr-ospf)# enable
tnsr(config-frr-ospf)# exit
tnsr(config)#

A similar configuration may be applied to neighboring routers also connected to the same network as the TenGigabitEthernet6/0/0 interface. Adjust the router ID and interface names as needed.

For a simple configuration such as this, a single area for all routers is typical.
