Route multicast traffic across vlans

Brian_Butts — Mon, 05 Oct 2015 11:07:00 GMT

I'm trying to route multicast traffic across two vlans - "things" and "wifipr". I've tried looking up documentation on this and I'm not really finding anything that resembles my situation. I'm not really sure where to start. I've tried enabling RIP, IGMP snooping, and IPMC forwarding but I don't think I've done enough. Here is my config on a x450e-24p. Any help is greatly appreciated. Thanks

RE: Route multicast traffic across vlans

Hi Brian,

If we want to route multicast traffic between different VLANs, we need IPMC routing protocols like PIM or MVR enabled.
We can decide which protocol to use depending on the design of the network.

MVR is simple to configure and if you are only looking for routing between these 2 vlans, then this would be a better option. However, if you are planning to scale up the multicast network, PIM could be considered.

The below article would help you get started with MVR configuration.

https://gtacknowledge.extremenetworks.com/articles/How_To/How-To-Configure-MVR

The match condition in the ACL should have the multicast IP address and the corresponding subnet mask. For example, if you want to allow only 239.0.0.0/8 addresses, include this address in the permit rule and 0.0.0.0/0 in the deny rule.

More information about PIM protocol can be referred in the user guide:

http://documentation.extremenetworks.com/exos/EXOS_All/IP_Multicast/c_pim-overview.shtml

Hope this helps!
