Hi guys,
I am not sure to have found a contradiction in the OSPF paper from
Certificationzone.
At first, Howard writes
". The BDR hears updates being sent to the DR and starts a timer. If the
DR does not respond before the BDR timer expires, the BDR will send out the
update that the DR should have sent. Under these circumstances, however, the
BDR does not take over as DR."
But pages later he says
"OSPF updates are actually sent to a multicast address that includes
both the DR and BDR. When the BDR hears an update sent to the DR, it starts
a timer. If the DR does not respond before the BDR's timer expires, the BDR
will assume that the DR is dead and will promote itself to DR."
Do you understand my confusion ?
Cheers.
