Configuring the source IP addresses for IGMP queries
After the switch 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 Layer 2 switch acts as the IGMP snooping querier, HP recommends you to configure a
non-all-zero IP address as the source IP address of IGMP queries.
IMPORTANT:
The source address of IGMP query messages might affect the IGMP querier election within the segment

3. Configure the source address
of IGMP general queries.

group-specific queries.

0.0.0.0 by default
Configuring IGMP snooping proxying
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 device works as the IGMP snooping proxy for the downstream hosts and upstream router in
the VLAN.
To enable IGMP snooping proxying in a VLAN:
