Thanks for taking a look. One thing I just noticed as I was doing this was
that R3 seems to have a limit on the number of OSPF adjacencies. It has
adjacencies with 2 other routers out that interface. (This is IEWB-DYN Lab
5). When I killed one of the other routers, suddenly the R2-R3 adjacency
came up. Then after a few minutes R3-R5 finally comes up. I don't know
what's going on now.

Subject: Re: OSPF adjacency problem (may be dynamips related)
Can you post your configurations for these two routers along with the
output of the show ip ospf neighbor and show frame-relay map commands from
each router?
