Step 9 Run:
igmp-snooping send-query source-address ip-address
The source address of the IGMP General Query message is configured.
By default, the source address of the IGMP General Query message is 192.168.0.1. When
192.168.0.1 is used by other devices on the network, you can run the igmp-snooping send-
query source-address command to change the source IP address of the IGMP General Query
message.

1.3.12 (Optional) Configuring the IGMP Snooping Proxy for the
VLAN
Context
After the IGMP proxy is configured on the S2700, the S2700 replaces the upstream router to
send IGMP Query messages to the downstream devices, and receives the IGMP Report and
IGMP Leave messages from the downstream devices. In this way, bandwidth consumption
between the upstream router and the S2700 is reduced and the workload on the upstream router
is also reduced.
Procedure

1.3.13 Checking the Configuration

Prerequisite
The configuration of IGMP snooping in a VLAN is complete.
Issue 01 (2011-07-15)
NOTE
After IGMP snooping proxy is enabled, the switch broadcasts IGMP Query messages to all interfaces in a
VLAN periodically, including the routing interfaces in the VLAN. This may result in the reelection of
IGMP querier. If the multicast network already has a querier, you are advised to use the igmp-snooping
proxy-uplink-port command to configure an interface as an IGMP snooping proxy uplink interface. No
IGMP Query message can be sent to this interface.
IGMP snooping proxy and IGMP snooping querier cannot be configured in the same VLAN.
