III. Configuration procedure
1) Configure Router B:
# Enable multicast.
[RouterB] multicast routing-enable
# Enable IGMP and PIM-DM on interfaces Ethernet0/0/0 and Ethernet1/0/0.
[RouterB] interface ethernet 0/0/0
[RouterB-Ethernet0/0/0] ip address22.22.22.1 24
[RouterB-Ethernet0/0/0] igmp enable
[RouterB-Ethernet0/0/0] pim dm
[RouterB-Ethernet0/0/0] igmp host-join 224.0.1.1
[RouterB-Ethernet0/0/0] interface ethernet 1/0/0
[RouterB-Ethernet1/0/0] ip address 33.33.33.2 24
[RouterB-Ethernet1/0/0] igmp enable
[RouterB-Ethernet1/0/0] pim dm
[RouterB-Ethernet1/0/0] quit
# Configure the interface Ethernet1/0/0 as the IGMP proxy interface of Ethernet0/0/0.
[RouterB] interface ethernet 0/0/0
[RouterB-Ethernet0/0/0] igmp proxy ethernet1/0/0
2) Configure Router A:
# Enable multicast.
[RouterA] multicast routing-enable
# Enable IGMP and PIM-DM on the interface Ethernet0/0/0.
[RouterA] interface ethernet 0/0/0
