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.
