Filter Multicast Traffic on VLAN

Hi group,

I was labbing up some multicast stuff. I just received a question to filter
multicast traffi of a specific group on a VLAN

Lab setup
          SW1
            |
 ----------------------------vl100
        | |
R4--SW2 SW3
        | |
       R5 R6

SW1, SW2 and SW3 are connected using a SVI interface VLAN 100
I use auto rp
SW1 = mapping agent
SW2 = RP for 232.5.5.5 and 232.55.55.55
SW3 = RP for 232.6.6.6
Loopback of SW1 has joined all the multicast groups above
R4 has joined multicast group 232.55.55.55

I want to filter out the 232.55.55.55 traffic on vlan 100 so SW1 does not
reply to the traffice and R4 does reply to that traffic
I tried igmp filters, but those are only availeble on access ports
I triend igmp access-group on all the vlan 100 SVI interface, but SW1 still
replies

What are my options to filter multicast traffic on a VLAN?

Thanks,

Kind regards,

Maarten Vervoorn
