Usage 
Information
You can configure an arbitrary value in the IP address for each router. However, each router ID

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.
