Check hello & dead times. They should be identical.

Check hello & dead times. They should be identical.

I just checked and my hello is 10 and my dead is 40.

I have distribution routers in Montreal and Toronto each supporting 34 access sites running OSPF over Frame Relay. Both Distribution routers are Cisco 3660's (12.2(1)). I am trying to bring up building number 35. This is a 2610 with 12.0(16). I can't get OSPF to go beyond INIT. I thought it may have been a circuit issue but layers 1 and 2 have both been accurately proved out. I am sending and receiving LMI, both pvcs are active, I am seeing the CIR; just no routing. Let me know if anyone has any suggestions. Thanks!

What type of OSPF network to you have your frame relay interfaces configured as?
01-21-2003 09:28 AM
Hello,
When using over frame-relay, your hello, dead timers need to match to that of the neighbors...Are you using multipoint subinterface at one end , and a point to point interface on other end..(over framerelay) ???, then the timers wont match in this case...For this you need to change the network type on the interfaces, using ("ip ospf network
To check to see what the problem is, give a "debug ip ospf adjacancies" on the 2600 router. or get back to us with that output...
Hope that helps

I would not recommend running the ospf debugs in a production enviroment. The potential is there to bring the box down.
Could you sh ow us the configs from both sides ?
try pinging 224.0.0.5 and source it from the outgoing interface see if you get a response . Also if you are using FR maps. make sure you have the broadcast key word at the end.

Sorry for the delay. Got pulled into something else. Here is the config on the access site. The hello and dead timers were left at their defaults. These are point to point. I did get a response from my remote sub-interface when I pinged 224.0.0.5 sourcing the outgoing interface.

what does sh ip o interface show ? are they in the same area ?
01-21-2003 11:17 AM
Yes. The area is 10.90.0.0. They are in the same area.
01-21-2003 11:34 AM
can you paste in the output of sh ip o interface
01-21-2003 10:48 AM
Make sure the MTU settings is the same on both interfaces.
01-21-2003 11:34 AM
I think that the best thing to do would be "debug ip ospf adjacancies" on the 2600 end to see what is going on. I wouldn't imagine it has to peer with too many other routers so you should be okay. But it is your network so you be the judge. If in doubt wait for after hours and/or use the "reload in 10" command in case you use connectivity.
Then post the results.
Hope it helps.

This is actually working now. I changed the DLCI mappings on the subinterfaces. For subinterface s0/0.420, I bound it to frame-relay interface-dlci 520 and vice versa and it worked. Thanks for everyone's input on this.
