Neighbors Stuck in Exstart/Exchange State The problem occurs most frequently when you attempt to run OSPF between a Cisco router and another vendor router. The problem occurs when the maximum transmission unit (MTU) settings for neighboring router interfaces do not match. If the router with the higher MTU sends a packet larger that the MTU set on the neighboring router, the neighbor router ignores the packet. When this problem occurs, the output of the show ip ospf neighbor command displays output similar to what is shown in this figure.

I don't know, man, but I'm just glad I'm not the one troubleshooting this. Probably need a couple of aspirin and a strong coffee to get through this one.

I agree with Earnestine, that could definitely cause the problem.

Nah, nah, nah, it's the hello intervals for sure. You know, the routers are probably just saying 'hello' at different speeds, like a couple of old farts who can't keep up with each other.

Good idea. Let's check that first before looking into anything else.

Maybe we should check and make sure they're set the same on both routers.

Yeah, you're right. It's probably the hello intervals causing the issue.

I think the issue could be mismatched OSPF hello intervals.

Hold up, I'm gonna go with the subnet settings. It's always the simple things that trip us up, am I right?

Hmm, I'd reckon it's the authentication settings. Gotta keep those bad boys in sync or else the whole network goes haywire.

Ah, the age-old OSPF adjacency woes. I'd bet my last dollar it's the MTU settings. Who even remembers to check those these days?
