InverVLAN MultiCasting

How do i enable InterVLAN MultiCasting. I have a WS-C3560G-24TS as my core switch and it does InterVLAN Routing. I have a Server VLAN (70) and Workstation VLAN (71). I have a server that i have set up to deploy  images to computers. Up to this point i have only done one computer at a time, so unicasting was ok. I would like to be able to Multicast to multiple computers, but am unsure what i need to do on the switch (if anything) to enable this.

Can you help?

Thanks.

If you need multicast, just enable PIM on vlan 70 and 71 SVIs.

So you are saying to do this:

Router(config)# ip multicast-routing distributed

Router(config)# interface VLAN70

Router(config-if)# ip pim passive

Router(config-if)# interface VLAN71

Router(config-if)# ip pim passive
