◆ This command sets the router ID for the OSPF process specified in the
router ipv6 ospf command.
◆ The router ID must be unique for every router in the autonomous
system. (Note that the router ID can also be set to 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 ipv6 ospf followed by the router ipv6 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.
◆ The current routing process will not be enabled until a Router ID is
configured with this command.
