Usage
Information
You can configure an arbitrary value in the IP address format for each router. However, each router ID
must be unique. If you use this command on an OSPF router process, which is already active (that is, has
neighbors), a prompt reminding you that changing the router-id brings down the existing OSPF adjacency.
The new router ID is effective at the next reload.
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]:
Dell#
