Hi Joseph,
why would I ever need the neighbor route? Is the connected not enough? It
looks great to me even without neighbor route....
Bit.
R2#show run
Building configuration...
interface Serial4/1
no ip address
dialer in-band
dialer pool-member 1
serial restart-delay 0
pulse-time 1
end
!
interface Dialer1
ip address 192.168.0.1 255.255.255.0
dialer pool 1
dialer idle-timeout 0
dialer persistent
end
R2#show ip route
C 192.168.0.0/24 is directly connected, Dialer1
R2#ping 192.168.0.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.0.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms

Yes, I tried it.
The only issue with HDLC (which ppp does automatically) is that it doesn't
install a route to the neighboring router's interface.
From a lab perspective, I fixed that with a static route, which wouldn't be
acceptable in general in the exam.
ppp does this automatically by installing a connnected route as part of ppp
negotiation.

Joseph,
Have you tried that solution? I couldn't get the loopback solution on to
the
hdlc link. It works on a ppp link.

Why not assign the IP to a loopback xx interface and use ip unnumbered
lo xxon the serial interafce?
