Re: Peer Neighbor Route

we do not need peer neighbor-route on ip address negotiated as long as we
have routing protocol configured. .

once we remove this peer neighbor-route command (on ip unnumbered ), then
we can cannot ping the ip address of the other end. But not to worry,
enable routing protocols, such as ospf will and it find a way to perform
the adjency then we can see the routes again (NOT in /32 but the actual
subnet mask)

for example

R1
int loopback 0
ip add 1.1.1.1 255.255.255.0
int s0/0
encap ppp
ip unnumbered loopback 0
no peer neighbor-route
sh
no sh
router ospf 1
net 1.1.1.1 0.0.0.0 a 0

R2
int loopback 0
ip add 2.2.2.2 255.255.255.0
int s0/0
encap ppp
ip unnumbered loopback 0
no peer neighbor-route
sh
no sh
router ospf 1
net 2.2.2.2 0.0.0.0 a 0

The ospf routing protocols will still works perfectly
