OSPF Bounces With Cisco Devices

[dane775]

I don't have a lot of info just yet, but apparently this problem has been going on for quite some time.

We're predominantly a Nortel shop but we've begun to introduce some Cisco WAN router's into our network. Prior to this we had a few Cisco Dial Servers and a CLAW/CIP router..(and maybe a few odds and ends)...not much.

Apparently we've always had issues where the OSPF adjacencies between our Cisco and Nortel devices bounced periodically. The analyst who worked on the problem a few years back had a case open with Cisco, but they were never able to pinpoint anything. They just gave up since it was only a few devices seeing problems.

Are there inherent issues between Nortel and Cisco devices with respect to OSPF??

Any help would be greatly appreciated.

What models of hardware are you using? I haven't had any problems with Nortel 8600 and Cisco 2600/3600/3800 series routers in a fairly generic configuration.

We've had issues with our Contivity 5000...and at least one of our BCNs. I'll have to check to see if we're losing adjacency with our 8600.

Thanks for the response...I'm working an Internet problem..but I'll check back once things settle a bit.

Check the MTU size of the cisco devices. This could cause the ospf problems.
the status stays stuck in exchange state when you encountered this issue.
