OSPF lab problem

jdballinger

So I'm watching the ICND2 CBT Nuggets, and trying to lab everything along with Jeremy. I just finished watching the OSPF configuration vid, and even though I followed along exactly, I can't for the life of me get it to work. I can form a neighbor relationship between R1 and R2, but when I do a 'show ip route' on R1, it isn't populated with any of the OSPF routes.



Here are the appropriate sections from the running configs for all 3 routers:

R1:

Any help would be very much appreciated, as I've wiped them and redone it a few times now with the same results.

Thanks!

"network 192.168.1.1 0.0.0.0 area 0" on R1 should be "network 192.168.1.1 0.0.0.255 area 0"

I had thought that at first too when I watched him do it in the video, but if all I'm advertising is that exact IP address it doesn't HAVE to be 0.0.0.255. Funny thing is that I just rebooted, and opened up the saved Packet Tracer file, and all of a sudden everything is working (with the configs I pasted above too.)

I don't understand why it didn't work before, but who cares, it works now!

Thanks anyways!

PT is known to have quirks like this. If something should work, a restart solves it a lot of times.
