Re: Broadcast ...

Dears,

IGMP Snooping is a method to "snoop/sniff" the IGMP Join/Leave/Query..etc
messages between the client & L3 Device. When a L2 switch is present only
which is connected to streamer/clients, on a layer 2 switchport you can
configure filtering as shown below:

int f0/10
 switchport mode access
 switchport access vlan 10
 ip igmp max-groups 5
 ip igmp filter 1
!
ip igmp profile 1
 deny
 range 232.0.0.0 239.255.255.255

Best Regards,
