Usually, this is done at the core level but is not necessarily so.

We need to be able to route multicast traffic between our server VLAN and our desktop VLAN. We plan on following this article:&nbsp;<A href="https://extremeportal.force.com/ExtrArticleDetail?an=000080491" target="_blank" rel="nofollow noreferrer noopener">https://extremeportal.force.com/ExtrArticleDetail?an=000080491</A> but we are wondering if this configuration needs to be done on all of the switches, or just the core x-460's?</P> Tue, 09 Oct 2018 20:12:00 GMT https://community.extremenetworks.com/t5/extremeswitching-exos-switch/routing-multicast-between-vlan-s-with-mvr/m-p/51705#M14169 Bruce_Garlock 2018-10-09T20:12:00Z https://community.extremenetworks.com/t5/extremeswitching-exos-switch/routing-multicast-between-vlan-s-with-mvr/m-p/51706#M14170 Hi Bruce,<BR /> <BR /> Generally, MVR wil be enabled on switches where source and destination VLANs are present as MVR is based on IGMP snooping.
