Loopback is advertised as a host route /32 instead of the actual subnet that is configured


Loopbacks are considered host routes in Open Shortest Path First (OSPF). 

To make OSPF advertise the loopback subnet as the actual subnet with the loopback mask, instead of as host route /32, issue the ip ospf network point-to-point command under the loopback interface.

For more information, refer to the 9.1. Interface States section of RFC 2328.
