MVR multiple switches, multiple vlans

GCIT_Support — Fri, 21 Jun 2019 02:44:57 GMT

We are running x460 (gen1). with default edge licensing. I need to be able to send multicast pages from Polycom VVX 400 IP phones. Pages need to go to multiple voice vlans across multiple switches. Is MVR possible solution for this? I have MVR working intra-switch, but cannot get it to work between switches. Any advise would be appreciated.

I have it working between 2 switches following this tech note:
https://gtacknowledge.extremenetworks.com/articles/How_To/How-to-configure-Static-MVR-regardless-of-IGMP-join/
Correct me if I am wrong, the idea hear is the multicast sender message is getting leaked thru a common vlan between the switches?

Hi GCIT_Support,

Yes, this article states that if there is multicast traffic comming in VLAN-A, the Static-MVR makes the mcast traffic to be leaked to VLAN-B with the MVR static configurations (which is naturally not supported without any multicast protocols such as PIM).

The article also states the way of using ACL to leak only particular multicast traffics that you want. In other word, all multicast traffic would be leaked to VLAN-B if there is no ACL configured.

Best regards,
David
