Configuring source IP addresses for IGMP queries
After a router receives an IGMP query whose source IP address is 0.0.0.0 on a port, it does not enlist that
port as a dynamic router port. This might prevent multicast forwarding entries from being correctly
created at the data link layer and eventually cause multicast traffic forwarding to fail. To avoid this
problem, when a router acts as the IGMP snooping querier, HP recommends that you configure a
non-all-zero IP address as the source IP address of IGMP queries.
Changing the source address of IGMP queries might affect the IGMP querier election within the subnet.

0.0.0.0 by default.
4. Configure the source IP
address for IGMP
group-specific queries.

0.0.0.0 by default.
Configuring IGMP snooping proxying
This section describes how to configure IGMP snooping proxying.
Configuration prerequisites
Before you configure IGMP snooping proxying in a VLAN, complete the following tasks:
Enable IGMP snooping in the VLAN.
Determine the source IP address for the IGMP reports sent by the proxy.
Determine the source IP address for the IGMP leave messages sent by the proxy.
Enabling IGMP snooping proxying
The IGMP snooping proxying function works on a per-VLAN basis. After you enable the function in a
VLAN, the router works as the IGMP snooping proxy for the downstream hosts and upstream router in the
VLAN.
