Step 4 Run:
igmp-snooping router-aging-time router-aging-time
The aging time of the router interface is set.
By default, the S9300 sets the aging time of the router interface as follows:
l
l
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.
Step 6 Run:
igmp-snooping require-router-alert
The S9300 is configured to process only the IGMP messages that contain the Router Alert option
in the IP header.
By default, the S9300 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 S9300 is configured to send the IGMP messages that contain the Router Alert option in the
IP header.
By default, the S9300 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.

Issue 01 (2009-07-28)
If the router interface receives an IGMP Query message, the S9300 sets the aging time of
the interface to 180 seconds.
If the router interface receives a PIM Hello message and the holdtime value of the Hello
message is larger than the remaining aging time of the interface, the S9300 sets the aging
time of the interface to the holdtime value contained in the PIM Hello message. If the holdtime
value is smaller than the remaining aging time of the router interface, the S9300 does not
change the aging time of the interface.
NOTE
The maximum response time must be shorter than the interval for sending IGMP General Query messages.
