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.
