Multicast VLAN configuration examples

Port-based multicast VLAN configuration

Network requirements

• As shown in Figure 20, Router A connects to a multicast source—Source—through Ethernet1/0/1,

and to Switch A through Ethernet1/0/2.

• IGMPv2 is required on Router A. IGMPv2 snooping is required on Switch A. Router A acts as the

IGMP querier.

• Switch A’s Ethernet1/0/1 belongs to VLAN 10, Ethernet1/0/2 through Ethernet1/0/4 belong to

VLAN 2 through VLAN 4 respectively, and Host A through Host C are attached to Ethernet1/0/2

through Ethernet1/0/4 of Switch A respectively.

• The multicast source sends multicast data to multicast group 224.1.1.1. Host A, Host B, and Host C

are receivers of the multicast group.

• Configure the port-based multicast VLAN feature so that Router A just sends multicast data to Switch

A through the multicast VLAN and Switch A forwards the multicast data to the receivers that belong

to different user VLANs.

Configuration procedure

1. Configure IP addresses

Configure the IP address and subnet mask for each interface according to Figure 20. T

he detailed

configuration steps are omitted here.

2. Configure Router A

# Enable IP multicast routing, enable PIM-DM on each interface, and enable IGMP on the host-side

interface Ethernet1/0/2.
