Re: DR election

Erblich,

I didn't get your reply, can u please give the references of the idea.

I mean to ask, is it possible to enforce DR/BDR-election without
changing configuration of existing DR/BDR?

Yes and no,

If a router "really wants to be the DR", the protocol does
allow this through a back door. The router must act like
it was already also elected as the DR. This can happen in
what was a split area. By coming up later, the later router
SHOULD know the other's priority and router-id. It can then
boost its broadcasted priority and/or its router-id to gurantee
re-election.
