R3303-HP 6600/HSR6600 Routers IP Multicast Configuration Guide

Configure IGMP snooping proxying on Router B, enabling the router 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.

Configuration procedure

1. Assign an IP address and subnet mask to each interface according to Figure 17. (Details not

shown.)

2. On Router A, enable IP multicast routing, enable PIM-DM on each interface, and enable IGMP on

Ethernet 1/1.

<RouterA> system-view

[RouterA] multicast routing-enable

[RouterA] interface ethernet 1/1

[RouterA-Ethernet1/1] igmp enable

[RouterA-Ethernet1/1] pim dm

[RouterA-Ethernet1/1] quit

[RouterA] interface ethernet 1/2

[RouterA-Ethernet1/2] pim dm

[RouterA-Ethernet1/2] quit

3. Configure Router B:

# Enable IGMP snooping globally.

<RouterB> system-view

[RouterB] igmp-snooping

[RouterB-igmp-snooping] quit

# Create VLAN 100, assign ports GigabitEthernet 2/0/1 through GigabitEthernet 2/0/4 to this

VLAN, and enable IGMP snooping and IGMP snooping proxying in the VLAN.

[RouterB] vlan 100

[RouterB-vlan100] port gigabitethernet 2/0/1 to gigabitethernet 2/0/4

[RouterB-vlan100] igmp-snooping enable

[RouterB-vlan100] igmp-snooping proxying enable

[RouterB-vlan100] quit
