IGMP proxying configuration example
Network requirements
As shown in
:
•
PIM-DM runs on the core network.
•
Host A and Host C in the stub network receive VOD information destined to multicast group
224.1.1.1.
Configure the IGMP proxying feature on Switch B so that Switch B can maintain group memberships
and forward multicast traffic without running PIM-DM.

Configuration procedure
1.
Assign an IP address and subnet mask to each interface according to
. (Details not
shown.)
2.
Enable IP multicast routing, PIM-DM, IGMP, and IGMP proxying:
# On Switch A, enable IP multicast routing, enable PIM-DM on VLAN-interface 101, and enable
IGMP on VLAN-interface 100.
<SwitchA> system-view
[SwitchA] multicast routing-enable
[SwitchA] interface vlan-interface 101
[SwitchA-Vlan-interface101] pim dm
[SwitchA-Vlan-interface101] quit
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] igmp enable
[SwitchA-Vlan-interface100] pim dm
[SwitchA-Vlan-interface100] quit
# On Switch B, enable IP multicast routing, enable IGMP Proxying on VLAN-interface 100, and
enable IGMP on VLAN-interface 200.
<SwitchB> system-view
[SwitchB] multicast routing-enable
[SwitchB] interface vlan-interface 100
[SwitchB-Vlan-interface100] igmp proxying enable
[SwitchB-Vlan-interface100] quit
[SwitchB] interface vlan-interface 200
[SwitchB-Vlan-interface200] igmp enable
