H3C S3600 Series Ethernet Switches-Release 1510 Chapter 6 IGMP Configuration
6-5
z On VLAN-interface2, configure VLAN-interface1 as the outbound IGMP Proxy
interface to external networks. You must enable the IGMP protocol on the interface
first, and then configure the igmp proxy command.
Configure Switch A as follows:
z Enable multicast routing and configure the IGMP protocol on VLAN-interface1.
z Configure the pim neighbor-policy command to filter PIM neighbors in the
network segment 33.33.33.0/24. That is, Switch A does not consider Switch B as
its PIM neighbor.
In this case, when Switch B of leaf network receives from VLAN-interface2 an IGMP
join or IGMP leave message sent by the host, it will change the source address of the
IGMP information to the address of VLAN-interface1: 33.33.33.2 and send the
information to VLAN-interface1 of Switch A. For Switch A, this works as if there is a host
directly connected to VLAN-interface1.
Similarly, when Switch B receives the IGMP general group or group-specific query
message from the Layer 3 Switch A, it will also change the source address of the query
message to the IP address of VLAN-interface2: 22.22.22.1 and send the message from
VLAN-interface2.
In
Figure 6-2, VLAN-interface2 of Switch B is called the client and VLAN-interface1 of
Switch B is called the proxy.
