R3303-HP 6600/HSR6600 Routers IP Multicast Configuration Guide

91
Configure the IGMP proxying feature on Router B so that Router 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 Figure 31. (Details not
shown.)
2. Enable IP multicast routing, PIM-DM, IGMP, and IGMP proxying:
# Enable IP multicast routing on Router A, PIM-DM on Serial 3/1/1, and IGMP on GigabitEthernet
2/1/1.
<RouterA> system-view
[RouterA] multicast routing-enable
[RouterA] interface serial 3/1/1
[RouterA-Serial3/1/1] pim dm
[RouterA-Serial3/1/1] quit
[RouterA] interface gigabitethernet 2/1/1
[RouterA-GigabitEthernet2/1/1] igmp enable
[RouterA-GigabitEthernet2/1/1] pim dm
[RouterA-GigabitEthernet2/1/1] quit
# Enable IP multicast routing on Router B, IGMP proxying on GigabitEthernet 2/1/1, and IGMP
on GigabitEthernet 2/1/2.
<RouterB> system-view
[RouterB] multicast routing-enable
[RouterB] interface gigabitethernet 2/1/1
[RouterB-GigabitEthernet2/1/1] igmp proxying enable
[RouterB-GigabitEthernet2/1/1] quit
[RouterB] interface gigabitethernet 2/1/2
[RouterB-GigabitEthernet2/1/2] igmp enable
[RouterB-GigabitEthernet2/1/2] quit
3. Verify the configuration:
# Display the IGMP configuration and operation information on GigabitEthernet 2/1/1 of Router
B.
[RouterB] display igmp interface gigabitethernet 2/1/1 verbose
GigabitEthernet2/1/1(192.168.1.2):
