    I am very new to this and I'm having some issues with understanding what part of this I'm miising. So my question is, How do I get my MSR954 act as the IGMP Quier for my layer 2 network switches?

    Hello @Dave6051 !

    IGMP querier should be enabled per L3 interface, e.g. routed port or Vlan-interface. In general all you need to do is to:

    1. Enable multicast routing (global command 'multicast routing')
    2. Enable IGMP on respective L3 interface (interface context command 'igmp enable'). By default IGMPv2 is enabled

    Example for Gig0/0 interface:

    system-view
    multicast routing
    interface Gig0/0
     ip address 10.0.0.1 24
     igmp enable

    After that if your router is the only IGMP device on this L3 network, it will become a querier. If there is another multicast router with IGMP enabled, then there is an querier election mechanism and the querier will be the router with lowest IP address.
