I have 2 data centres connected across a Spine/Leaf fabric using BGP EVPN. In one DC I have UCS and in the other legacy Dell servers running ESX conected to catalyst switches. These are trunked via a VPC to the local 9k leafs to interconnect with the fabric. Some of the Vlans have L2 multicast running. All the relevant Vlans are bridged across the fabric and presented to UCS/ESXi. When the VMs' were vmotioned across everything worked fine except the multicast broke. I created a Multicast Policy in UCS and enabled the querier with an IP address in one of the relevant Vlans as from cisco documentation UCS will not forward the traffic unless an mrouter/querier exists. I then attached the policy to the relevant Vlan under the LAN section. However still not working. I dont see any querier information on the directly connected upstream switches either. Does IGMP querier need enabling on the switches ?
