Message-ID: <86da31a8-1d6e-d974-708d-a8c3b9358b61@shout.net> Howdy all ... Curious if anyone has had any success doing a static IGMP join on an Arista switch ... In this case we're talking about a 7050TX running 4.21.8M. We have an IPTV box downstream which, in my opinion, should be sending its own joins, but that's another rant. All of the IGMP settings switch-side look fine to me, and, when it does work (another rant), I can see everything propagating upstream as it should. They're suggesting we do the join ourselves switch-side facing the physical ethernet port on which the IPTV device is attached. Turned the google crank a few times and found some suggestions, but no joy yet. Curious if anyone has made this work ... thanks!! - bryan From sabri at cluecentral.net Mon Mar 2 14:09:31 2020 From: sabri at cluecentral.net (Sabri Berisha) Date: Mon, 2 Mar 2020 11:09:31 -0800 (PST) Subject: [a-nsp] static multicast join?

However, in this particular case, the Arista port is Layer 2 only on an access-port assigned to a VLAN. I've tried the 'ip igmp static-group' command, but nothing happens. Thoughts?

I think joins by definition can only be done by l3 interfaces. In this case I think you?d have to do it on the VLAN virtual interface. L2 interfaces can only do igmp snooping. -- patrick From bryan at shout.net Mon Mar 2 14:46:16 2020 From: bryan at shout.net (Bryan Holloway) Date: Mon, 2 Mar 2020 20:46:16 +0100 Subject: [a-nsp] static multicast join?

The far-side L3 interface is several switches upstream, and, while I can successfully create static joins from it, nothing propagates downstream because the recalcitrant device won't send joins.

That will give you a lot more flexibility.
