I have a 3550 layer 3 switch with 4 different vlans.
One of the vlans is multicasting its audio/video on the 224.x.x.x
in which all my pcs on that network can recieve audio and video.
th problem is that the multicast is not being forward to the other vlans so no pc on the other vlans get recieve the a/v. I know vlans dont pass multicasts outside of it own vlan...but it can be done.. how do i get the other vlans to get the multicast. Could it be to enable IGMP spoofing..or setting up MVR( which I dont think is the case, because there is no actual physical router involved)

Here are a couple of docs that might help you out :

www.cisco.com/univercd/cc/td/doc/product...18a/config/multi.pdf

www.intelligraphics.com/articles/ipmulticasting2_article.html

I haven't done any hardcore research, so if you figure something out then post your results it'll be interesting.

It was neitherof the two options, Look through the "Cisco Routers for IP Routing Little Black Book: The Definitive Guide to Deploying and Configuring Cisco Routers
by Innokenty Rudenko " Nice book by the way.

I found that I need the the commands

(config)#ip multicast-routing {which enables it on that switch}

then on each vlan(interface) in which i wanted to recieve or pass multicasts

(config)#config vlan2
(config-if)#ip pim dense-mode

Worked like a charm. :D
Since i had a layer 3 switch with ip routing, i could use the router commands on the switch. I also have two switches connected to that switch and am using port trunking so each switch will share its info.

Full IP routing with no router....sweet

You can only use the router functions if you have the Multilayer Image options.
Thanks,
