Disable or Reenable Peer Neighbor Routes
The Cisco IOS software automatically creates neighbor routes by default; that is, it automatically sets up a route to the peer address on a point-to-point interface when the PPP IPCP negotiation is completed.
To disable this default behavior or to reenable it once it has been disabled, use the following commands in interface configuration mode:
Command Purpose
no peer neighbor-route
Disable creation of neighbor routes.
peer neighbor-route
Reenable creation of neighbor routes.
is that what you are after ?
