Troubleshooting IP Unnumbered Interface
To understand how to debug connect host polling, see the Cisco IOS documentation of the debug arp
command on cisco.com.
When an IP unnumbered interface shares the IP address of a loopback interface whose prefix is
advertised in an OSPF network, you must modify the loopback interface as a point-to-point interface.
Otherwise, only the loopback interface host route is advertised to an OSPF neighbor.
Switch(config)# int loopback 0
Switch(config-if)# ip address
Switch(config-if)# ip address 10.1.0.1 255.255.0.0
Switch(config-if)# ip ospf network point-to-point
Switch(config-if)# end
