First post here.

In brief I have VLAN 1102 which is used as a multicast source VLAN. This has an IP multicast boundary to only allow out multicasts to receivers in VLAN 1101. The reason for doing this was to try and stop the flooding of multicast traffic in 1101 but this hasn't solved the issue and I'm trying to find out why.

I have had a quick look and cant really find what exactly the number of matches in the brackets means. In the permit case, does the match number indicate the number IGMP requests allowed? In the deny case, is it the number of multicast addresses blocked by the ACL?

Here's the ACL. Any help would be appreciated.

Standard IP access list IGMP1102

The number is the number of packets that matched the particular ACE (line). So for example, there were 37,414 packets that matched line 10.
