[c-nsp] problems filtering multicast

[William]

Hi,

I'm running multicast routing with sparse-dense-mode and I'd like to
filter out some of the addresses, I've created a standard access list
permitting the multicast addresses i want to be routed out and then a
deny any at the end.

I've applied it to the interface using the ip igmp access-group
<ACLNAME> command but it doesn't seem to be affective, the end hosts
are still receiving the multicast streams which i've attempted to
filter out.

The hardware is a 6500 (catos) with a sup2, the configuration looks
like so on the first switch:

interface vlan999
ip address 192.168.99.254255.255.255.0
ip pim sparse-dense-mode
ip igmp access-group multicast


 ip access-list standard multicast
 permit 239.255.1.1
 deny   any

The end host is on a 3750, I tried applying the access-list and ip
igmp access-group statement to the vlan interface where the end host
is and the multicast traffic that I wish to be filtered is still
coming over.

Am I doing something terribly wrong here for it not to work?

Thank you for your time.
