3560 Multicast Cross-VLAN Traffic

[vbahuse]

I have two 3560's setup with vlans, inter-vlan routing (static), hsrp, and require multicast traffic to be routed between two vlans. Can this be done?

My first guess would be something like:

ip route 239.100.3.1 255.255.255.255 Vlan3
ip route 239.100.4.1 255.255.255.255 Vlan4

where the recipient of 239.100.3.1 would exist on Vlan3 and 239.100.4.1 on Vlan4. Am I way off base or on the right track?

After this is working how would I then subscribe ports to a multicast address so that the traffic doesn't get sent everywhere on the destination vlan?

Cheers,

No have to set up multicast routing on your 3560. Quite a bit more involved.

You have confirmed my fear... Thanks for the link! I will start digging in

First major gotcha is that only the IP Services (& Advanced IP Services) support inter-VLAN Multicast routing. The IP Base image only supports IGMP Snooping and you can't get Multicast to pass between VLAN's unless you use PIM Stub. PIM Stub is designed for Layer-3 in the access-layer - i.e. local VLANs and routed uplinks to the distribution/core layer..
