◆ This command sets the router ID for the OSPF process specified in the
router ospf command.
◆ The router ID must be unique for every router in the autonomous
system. Using the default setting based on the highest interface
address ensures that each router ID is unique. (Note that the router ID
can also be set to 0.0.0.0 or 255.255.255.255).
◆ If this router already has registered neighbors, the new router ID will
be used when the router is rebooted, or manually restarted by entering
the no router ospf followed by the router ospf command.
◆ If the priority values of the routers bidding to be the designated router
or backup designated router for an area are equal, the router with the
highest ID is elected.
