Command Usage

•The router ID must be unique for every router in the autonomous system. Using the default setting based on the lowest interface address ensures that each router ID is unique. Also, note that you cannot set the router ID 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.

Example

Console(config-router)#router-id 10.1.1.1
