Multicast filter

I have implemented the multicast on a few switch. Have enabled "ip multicast routing" and "ip pim sparse-mode" on interface vlan 10 and 20.

With the sniffer I have traced the multicast source and have seen that it is 224.3.100.101.

Can I create a filter to allow the passage of only this multicast address?

I thought I would do so:

interface vlan 10

ip pim sparse-mode

ip multicast boundary 4

access-list 4 permit 224.3.100.101

IT's right?

Thanks for your help

Re: Multicast filter

I believe you would need something like:

access-list 101 permit ip any host 224.3.100.101 (or something to that effect.)

Peter Welcher wrote a good article about just this kind of thing:
