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.

D) mismatched subnet settings on the OSPF interfaces sounds like the likely culprit here. If the subnets don't match, how can the routers even establish a connection?

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

I think the issue could be mismatched OSPF hello intervals.
