Re: DR priority in multicasting

Isnt this the way? but if the metric and AD towards the source is the same
Highest IP address on the segment wins.! thats basicallythe DR aint it?
Assert Message
The assert message is used to determine which router will be responsible to
forward multicast group traffic onto a LAN segment, when multiple routers
are capable of performing the task. (I.E., one of the router will assert
themselves over the others.)
Routers on a segment will know this situation has arisen if they see each
others forwarded multicast traffic on the same segment. When that happens,
they send assert messages to one another.
The router will win based on the administrative distance and metric of the
unicast route covering the multicast source.
The router with the lowest administrative distance wins.
If tied, the router with the lowest advertised metric wins.
If still tied, the router with the highest IP address on that LAN segment
wins.
