Blocking Multicast stream

Hi,

I Have configured PIM sparse mode for few vlans and it is working fine.

I would like to give multicast feed only certain users and block for others within each VLAN.

Is there any way to implement user level access?

Thanks in advance.

Regards, Rajesh

Re: Blocking Multicast stream

Hello Rajesh,

you can use the command 'ip igmp access-group' on your VLAN interfaces, in order to control who can access which multicast group. Let's say you want only host 192.168.1.10 on VLAN 4 to be able to join multicast group 225.1.1.1, the configuration would look like this:

access-list 100 permit igmp host 192.168.1.10 host 225.1.1.1

!

interface VLAN4

ip igmp access-group 100

HTH,

GNT
