H3C S9500 Series Routing Switches
Switch A processes the message after receiving the IGMP message sent by
Switch B through the interface of VLAN 100, just as the message is sent by a host
directly connected to the interface of VLAN 100.
The procedures to process IGMP normal group or specific group querying messages
are as follows:
After receiving a normal group or a specific group querying message from Switch
A, Switch B changes the source address of the querying message to the address
of the outbound interface leading to hosts.
Switch B transmits the message through the interface of VLAN 200.

5.2 IGMP Configuration

After the multicast function is enabled, you must enable IGMP on the interface first and
then perform other IGMP configurations.
1) IGMP basic configuration includes:

Enabling multicast

Enabling IGMP on an interface

2) IGMP advanced configuration includes:
Configuring a router to join specified multicast group
Configuring the IGMP query message interval
Configuring the IGMP version
Configuring the IGMP querier present timer
Configuring the maximum query response time
Configuring the times of sending IGMP Group-Specific Query packet
Configuring the interval of sending IGMP Group-Specific Query packet
Configuring the limit of IGMP groups on an interface
Deleting IGMP Groups Joined on an Interface
Configuring the Filtering Rule of Multicast Groups
Enabling/Disabling IGMP Fast Leaving
5.2.1 Enabling Multicast
Only if the multicast function is enabled can the multicast-related configurations take
effect.
Refer to 4.2.1 Enabling Multicast Routing.
5.2.2 Enabling IGMP on an Interface
This configuration task is to enable IGMP on the interface which needs to maintain the
multicast membership. After this, you can initiate IGMP feature configuration.
Perform the following configuration in VLAN interface view.
