Command History

Version	Description
9.9(0.0)	Introduced on the FN IOM.
9.2(0.0)	Added support for OSPFv3.
8.3.16.1	Introduced on the MXL 10/40GbE Switch IO Module.

Usage Information

You can configure an arbitrary value in the IP address for each router. However, each router ID must be unique.

If this command is used on an OSPFv3 process that is already active (has neighbors), all the neighbor adjacencies are brought down immediately and new sessions are initiated with the new router ID.

Example

Dell(conf)#router ospf 100
                                             Dell(conf-router_ospf)#router-id 1.1.1.1
                                             Changing router-id will bring down existing OSPF adjacency [y/n]:
                                             
                                             Dell(conf-router_ospf)#show config
                                             !
                                             router ospf 100
                                             router-id 1.1.1.1
                                             Dell(conf-router_ospf)#no router-id
                                             Changing router-id will bring down existing OSPF adjacency [y/n]:
