Huawei quidway s7700 - Optional) Configuring the IGMP Snooping Proxy for the VLAN

value is smaller than the remaining aging time of the router interface, the S7700 does not
change the aging time of the interface.
Step 5 Run:
igmp-snooping max-response-time max-response-time
The maximum response time for IGMP messages is set.
By default, the maximum response time for IGMP messages is 10 seconds.
NOTE
The maximum response time must be shorter than the interval for sending IGMP General Query messages.
Step 6 Run:
igmp-snooping require-router-alert
The S7700 is configured to process only the IGMP messages that contain the Router Alert option
in the IP header.
By default, the S7700 can process the IGMP messages that do not contain the Router Alert option
in the IP header from a VLAN.
Step 7 Run:
igmp-snooping send-router-alert
The S7700 is configured to send the IGMP messages that contain the Router Alert option in the
IP header.
By default, the S7700 sends the IGMP messages that contain the Router Alert option in the IP
header.
Step 8 Run:
quit
The system view is displayed.
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.

2.3.12 (Optional) Configuring the IGMP Snooping Proxy for the
VLAN
Context
After the IGMP proxy is configured on the S7700, the S7700 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 S7700 is reduced and the workload on the upstream router
is also reduced.
