Figure 29-10. Command Example: show ip ospf process-id interface
Loopback interfaces also assist in the OSPF process. OSPF will pick the highest interface address as the
router-id and a loopback interface address has a higher precedence than other interface addresses.
Figure 29-11 gives an example of the
show ip ospf process-id interface command with a Loopback
interface.
