This one's kicking my ass. Should be simple, but apparently it isn't. I've
got three routers in a frame relay configuration: R3 is the hub, R4 and R5
are the spokes. For some reason the routes aren't being exchanged the way
they should be, in spite of the fact that all the OSPF adjacencies *appear*
to be there. R5 isn't getting any OSPF routes, and yet R4 (which has the
exact same configuration) is getting a couple from R3. Below you'll find
the configs, routing tables, and neighbor statuses for all three routers.
