SVI can't become an OSPF neighbor?

Sorry if this is obvious to some, but for the life of me, I cannot figure it
out...

When I try to add a switch SVI subnet to the OSPF process, it will not
neighbor up with the other 2 routers on the same subnet. I can see in the
debug that it keeps trying to win the DR/BDR election (and eventually does
due to highest IP address), but it will never establish with the other
devices.

The other 2 routers, in the meantime, work just fine until the switch is
added (which is always stuck in EXSTART from the router perspective). Then,
when the switch becomes the DR, the other routers will start losing their
own neighborships with each other (obviously).

What in the world am I doing here? I feel like I've done this scenario so
many times in the past, and without complications...

Is it me, or the equipment? :)

Thanks,

Ed
