IGMP Snooping on MX devices

[LouisR]

Quick question for the community, we had a request to disable IGMP snooping for some of our sites. The few that had switches we were able to go in and disable this in the switch settings. But for the sites that are only running a MX device is this an issue? Do MX devices participate in IGMP snooping or only switches?

There isn't any setting that I've ever come across on the MX for anything to do with IGMP etc.

From the doc: https://documentation.meraki.com/zGeneral_Administration/Other_Topics/Multicast_support

IGMP Support on the Cisco Meraki Security Appliance

MX Security Appliances will forward IGMP traffic for a single broadcast domain. It does not forward multicast traffic upstream, between VLANs, or over a VPN.

Yea I looked over that documentation so I think my take away looks to be correct. Thank you everyone.
