OSPF uses a router ID in it's advertisements to other neighbors.
The router id is simply the highest IP address of a loopback if you
have them configured and if not then the highest IP of an active
interface. I don't think it's a reachability type question - the
neighbors certainly need to
Hi all,
Two routing protocols: OSPF and EIGRP DO need to have their own router
ID reachable by other routers to have proper network connectivity, or am
I incorrect?
Any confirmation on this is much appreciated.
