Quick Notes - PPP no peer neighbor-route

Peer neighbor routes are required when the PPP neighbors IP address is on a different subnet. This will create a host connected route in the routing table. When both peers IP address are on the same subnet then use "no peer neighbor-route". A couple of scenarios where you may have peer neighbors in different subnets include:
-Virtual-template interfaces
-IP unnumbered interfaces
-Multilink interfaces
-IPCP negotiated address

"peer neighbor-route" is enabled by default.
