You can set the source IP addresses in the IGMP reports and leave messages sent by the IGMP snooping
proxy on behalf of its attached hosts.

Configuring an IGMP snooping policy

Prerequisites

Before configuring an IGMP snooping policy, complete the following tasks:
Enable IGMP snooping in the VLAN
•
Determine the ACL rule for multicast group filtering
•
Determine the maximum number of multicast groups that a port can join
•
Determine the 802.1p precedence for IGMP messages
•

Configuring a multicast group filter

On an IGMP snooping–enabled router, the configuration of a multicast group allows the service provider
to define restrictions on multicast programs available to different users.
In an actual application, when a user requests a multicast program, the user's host initiates an IGMP
report. After receiving this report message, the router checks the report against the configured ACL rule. If
the port on which the report was received can join this multicast group, the router adds an entry for this
port in the IGMP snooping forwarding table. Otherwise, the router drops this report message. Any
multicast data that has failed the ACL check will not be sent to this port. In this way, the service provider
can control the VOD programs provided for multicast users.
Use the command...
system-view
vlan vlan-id
igmp-snooping proxying enable
Use the command...
system-view
vlan vlan-id
igmp-snooping report source-ip
{ ip-address | current-interface }
igmp-snooping leave source-ip
{ ip-address | current-interface }
