Hi Bob,
I tried your solution given below and it doesnt seem
to work:
~~~~
no ip igmp snooping vlan 1
mac-address-table static 0100.5e40.0101 vlan 1
interface FastEthernet0/3
~~~~
Looks like even snooping is disabled, mac address is
learnt at the switch. Correct me if i am wrong.
Thanks & Regards,
Ashok M A

Gladston,
Either of those two scenarios will work. You can
block the igmp membership reports with igmp filters on
each disallowed layer 2 interface. If you are using
routers to simulate the host, do not configure PIM on
the interface.
The mroute table on the upstream router should not
indicate a connected host on that interface.
You could also disable igmp snooping for the vlan and
hard-code the multicast mac to the permitted
interfaces, like so:
no ip igmp snooping vlan 1
mac-address-table static 0100.5e40.0101 vlan 1
interface FastEthernet0/3
