[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 GigabitEthernet 2/0/1 through GigabitEthernet 2/0/4 to this VLAN,

and enable IGMP snooping and the function of dropping unknown multicast traffic 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 drop-unknown

[RouterB-vlan100] quit

# Configure a multicast group filter so that the hosts in VLAN 100 can join only the multicast group
