I forgot to set the ip ospf priority to 10 on R1 and 0 on R2 and R3.


A couple things I noticed this time around....

O stands for in the area and O IA is from a different area.

R2#sh ip ospf nei

10.3.3.3 1 FULL/DR 00:00:37 192.168.20.3 Ethernet0

R3 is the Dr, because 10.3.3.3 is greater than 10.2.2.2.



R2#debug ip ospf hello
00:44:20: OSPF: Rcv hello from 10.1.1.1 area 1 from Serial1 192.168.12.1

I was very confused as to why I wasn't forming an adjacency on frame-relay. I need to add neighbor commands to R2 and R3. I also had to use the frame-relay interface (s0).
