Igmp Snooping Proxying Configuration Example - HP MSR ASM Configuration Manual

[SwitchA-vlan100] quit
2. Configure Switch B:
# Enable IGMP snooping globally.
<SwitchB> system-view
[SwitchB] igmp-snooping
[SwitchB-igmp-snooping] quit
# Create VLAN 100, and assign Ethernet 1/1 through Ethernet 1/4 to the VLAN.
[SwitchB] vlan 100
[SwitchB-vlan100] port ethernet 1/1 to ethernet 1/4
# Enable IGMP snooping and the function of dropping unknown multicast traffic in VLAN 100.
[SwitchB-vlan100] igmp-snooping enable
[SwitchB-vlan100] igmp-snooping drop-unknown
[SwitchB-vlan100] quit
Configurations on Switch C and Switch D are similar to the configuration on Switch B.
Verifying the configuration
After the IGMP snooping querier starts to work, all the switches but the querier can receive IGMP general
queries. By using the display igmp-snooping statistics command, you can display statistics for the
received IGMP messages. For example:
# Display statistics for the IGMP messages on Switch B.
[SwitchB] display igmp-snooping statistics
Received IGMP general queries:3.
Received IGMPv1 reports:0.
Received IGMPv2 reports:12.
Received IGMP leaves:0.
Received IGMPv2 specific queries:0.

IGMP snooping proxying configuration example

Network requirements
An MSR with a fixed Layer 2 Ethernet switching interface or a Layer 2 switching interface module acts as
a switch (Switch A in
As shown in
serves as an IGMP querier.
Configure IGMP snooping proxying on Switch A, enabling the switch to forward IGMP reports and leave
messages on behalf of attached hosts and to respond to IGMP queries from Router A and forward the
queries to the hosts on behalf of Router A.
IGMPv2 specific queries:0.
IGMPv3 specific queries:0.
IGMPv3 specific sg queries:0.
