feature request: per protocol instance router id

[Csaba Szép]

Hi!

Now the router id is global option, it would be great if that is
configurable per (ospf) protocol instance like cisco.

router ospf 1
 router-id 2.0.0.1
 log-adjacency-changes
 area 0.0.0.0 authentication message-digest
 redistribute static subnets
 network 2.0.0.0 0.0.0.255 area 0.0.0.0
 default-information originate

Any chance?

thx
