History

Introduced on the MXL 10/40GbE Switch IO Module.
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
