Usage Information You can congure an arbitrary value in the IP address format for each router. However, each router ID must
be unique. If you use this command on an OSPF router process, which is already active (that is, has
neighbors), a prompt reminding you that changing the router-id brings down the existing OSPF adjacency.
The new router ID is eective at the next reload.
