ROUTER OSPFv3 for OSPFv3
Command
History
Version 9.2(0.0)
Added support for OSPFv3.
Version 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]:
