Using a neighbor command with a P2P subinterface doesn't help you unless
you're running in non-broadcast mode!
Which, according to the solution (which I think got truncated):
interface Serial0/1/0.24 point-to-point
description Frame Relay Cloud 2
ip address 150.50.24.2 255.255.255.0
ip access-group NewStuff-In in
ip access-group NewStuff-Out out
ip ospf network non-broadcast
ip ospf priority 100
frame-relay interface-dlci 204
Therefore it's there...
Now, I don't have the lab book with me, but two things leap to mind...
1. Did the lab say that the hub router had to be the DR on all links or
something like that?
2. Were you not allowed to change the interface type on the spoke side
(which as a physical link would default to non-broadcast)
3. Perhaps there were drugs involved, or just a desire to show a different
configuration
It's not WRONG to do it that way. :)

Subject: Pre lab 9 ipexpert work book ver.8 R & S
Hello everyone,
I did the pre lab # 9 in Ipexpert work book version 8 R & S.
My answer is slightly different from what they have when I checked the
solution. Below is my result. The problem with my when I do : show ip route
on R2 I dont see the loopback 0 of R4 in the routing table but I see
R5,R6,R7,R8 and R9 on the other when I do show ip route on R4 I dont see
any loopback advertise in the routing table. I cant ping the loopback0 of
R4 either vice versa.
Do I missing something here?
I also see I dont seem to understand with ipexpert solution. They are
using sub-interface point-to-point on R2 to R4 using frame-relay
interface-dlci command and in their ospf router configuration they have
check below. My big question is. Why theyre using neighbor command to R4. I
thought neighbor command cant be used on point-to-point.
Please advice.
Tandou,
