Yeah, that's how we have it set. Each router has a unique router ID. Our main router has one ID, but has a dozen or so ospf neighbors. We've been running this setup for quite a while. Doesn't seem like we saw it until an upgrade a while back. We do have a loop in our network, on purpose, that OSPF routes around for primary and redundant. However, all of the IP's that are showing in the logs aren't part of the ring. They are all legs/stubs of the ospf, not anything to do with the ring.
