We currently have a querier (v3) running on VLAN 400 and it perfectly works for multicast group joins within that VLAN. However when performing a source specific group join it seems to forward traffic from other sources as well.

My transmitting part is sending on group with source address
My receiving part is subscribed to group with source address

There is not multicast traffic to group from source; Expected result is that no multicast packets would be received, but it receives all traffic from What configuration is required to enable source specific multicast on the same VLAN?

arista(config)#show ip igmp snooping querier detail
Vlan IP Address Version Port
400 v3 Switch

arista(config)#show ip igmp snooping querier membership
Vlan: 400 Elected: QQI: 5 QRV: 2 QRI: 5 GMI: 15
