OSPF between RB450G (v5.1) and a Cisco 6509

Thu Apr 21, 2011 6:01 am

I have been testing out various routing protocols between a RB450G running v5.1 and a 6509.
BGP played very well, even in a confederation setup. Heck, it seemed that the RB450G took in a full internet routing table (~355K routes) with ease, where my C7204VXR (NPE-400, 512M RAM) was a bit sluggish taking in all those routes.

However, I am not having a good time with OSPF, trying to neighbor up to a 6509 (SUP720-3B, 12.2.33 SXI)
Here is my config on both devices. .20 is the MT (ether1) and .18 is the 6509.

It seems that something is blocking the broadcast. I put in an accept filter for the OSPF protocol but that didn't seem to help.

Any pointers anyone? I just want to see the neighborship establish - I am going to work passing routes between them later on.

Quick glance - but your instance ID on the interface is set to 13, probably to match the process number in the 6k. Process numbers don't have to match, and if you do a "/routing ospf instance print" you'll find you only have an instance 0. Set the instance ID on the interface to 0 and the neighbor should come up.

Fewi - you were dead on; that was it. My edge and core neighbor routers came right up on MT after changing that instance from 13 to 0.

Now on to the announcement tweaking... Thanks again,
