Broadly speaking, when the switch sees IGMP queries coming in on a port, it marks that port as a router port and floods all multicast traffic up it. > > Could any answers please be copied to my direct email as well as the list, > as I only get digests. > > > Thanks, > > Michael. > -- > Michael Robson, | Tel: 0161 275 6113 > Networks, | Fax: 0161 275 6040 > University of Manchester. | Email: [EMAIL PROTECTED] > > Youth and skill are no match for experience and treachery. > > > _______________________________________________ > cisco-nsp mailing list [email protected] > https://puck.nether.net/mailman/listinfo/cisco-nsp > archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
