I am doing the last OSPF CBT Video / Lab.
Jeremy has you setup a large multi area ospf topology. I am not far in but ran into a snag. For some reason I cannot figure out why I cannot see loopbacks from R3 in R2's routing table and or any other router that should see them, like R1. This has got to be something simple but its killing me. FYI Jermey basically has you setup loopbacks to simulate additional networks in the area.
Any ideas what I am missing that is prevent me from seeing the 172.30.x.x routes (my loopbacks) in R2's table and or any other routers that should see them? I am assuming its something that isn't configured right on R3 however I have provided configs for R3, R2, and R1.
Configs:

Hi Danielh,
I've only looked at this briefly so there might be more than one problem, but I've seen the following:
- Check your OSPF configuration on R2 and R3 for the point-to-point link between the two routers. On R3 you have configured the area ID as 23 and on R2 you have configured it as 24.

HAHA! You are good! I swear I looked at the configs on the affecting routers for quite a while. I Can't believe I didn't catch this!! Thanks so much! That was the problem. After configuring R2 for area 23 instead of 24 like it should be, everything worked.
Silly me. Thanks again!Currently Studying: IE Stuff...kinda...for now...
