Configuring the source IP addresses for the IGMP messages
sent by the proxy
You can set source the IP addresses for the IGMP reports and leave messages that the IGMP snooping
proxy sends on behalf of its attached hosts.
To configure the source IP addresses for the IGMP messages sent by the proxy in a VLAN:
Step
1. Enter system view.
2. Enter VLAN view.
3. Configure the source IP
address for the IGMP
reports that the proxy sends.
4. Configure the source IP
address for the IGMP leave
messages that the proxy
sends.

Configuring IGMP snooping policies

This section describes how to configure IGMP snooping policies.

Configuration prerequisites

Before you configure IGMP snooping policies, complete the following tasks:
Enable IGMP snooping for 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, you can configure a multicast group filter to limit multicast
programs available to users.
In an application, when a user requests a multicast program, the user's host initiates an IGMP report.
After receiving this report message, the IGMP snooping-enabled router resolves the multicast group
address in the report and looks up the ACL. If a match is found to permit the port that received the report
to join the multicast group, the IGMP snooping-enabled router creates an IGMP snooping forwarding
entry for the multicast group and adds the port to the forwarding entry. Otherwise, this router drops this
