IGMP proxying configuration example
1. Network requirements
PIM-DM runs on the core network. Host A and Host C in the stub network receive VOD information
sent to multicast group 224.1.1.1.
Configure the IGMP proxying feature on the firewall so that the firewall can maintain group
memberships and forward multicast traffic without running PIM-DM.
Figure 339 Network diagram
2. Configuration procedure
a. Assign an IP address and subnet mask to each interface according to Figure 339. (Details not
shown.)
b. Enable IP multicast routing, PIM-DM, IGMP, and IGMP proxying:
# On Router
A, enable IP multicast routing globally, PIM-DM on Serial 2/1, and IGMP on
Ethernet 1/1.
<RouterA> system-view
[RouterA] multicast routing-enable
[RouterA] interface serial 2/1
[RouterA-Serial2/1] pim dm
[RouterA-Serial2/1] quit
[RouterA] interface ethernet 1/1
[RouterA-Ethernet1/1] igmp enable
[RouterA-Ethernet1/1] pim dm
[RouterA-Ethernet1/1] quit
# On the firewall, enable IP multicast routing globally, IGMP proxying on GigabitEthernet 0/1,
and IGMP on GigabitEthernet 0/2.
<Firewall> system-view
[Firewall] multicast routing-enable
[Firewall] interface gigabitethernet 0/1
[Firewall-GigabitEthernet0/1] igmp proxying enable
