OSPF, pulling hair out...

From: Al Banks (abanks@xxxxxxxxxxxxxx)
Date: Tue Oct 24 2000 - 11:01:40 GMT-3


   
OSPF, over frame - one spoke and the hub form the neighbor relationship, no
problem. The other spoke doesn't - they stay in attempt/drother and
init/drother. All interfaces have "ip ospf network non-broadcast"
configured, all are pingable, and I've got the appropriate neighbor
statements.

>From the states, it looks like the hub (the one in attempt) is sending
hellos, but not getting any. The spoke (init) is getting hellos, but
doesn't see itself. The router ID on all of these is the serial interface
address (199.16.236.R#)

Any ideas why this is happening, or do I just need to go get some more sleep
and less coffee?

I've attached the configs - R3 is the hub, R6 is the misbehaving one, and R2
is the good one.

Thanks!
