Port-Based Multicast VLAN Configuration
Network requirements
z
As shown in
, Router A connects to a multicast source (Source) through GigabitEthernet
2/0/1, and to Switch A through GigabitEthernet 2/0/2.
z
IGMPv2 is required on Router A. IGMPv2 Snooping is required on Switch A. Router A acts as the
IGMP querier.
z
Switch A’s GigabitEthernet 2/0/1 belongs to VLAN 10, GigabitEthernet 2/0/2 through
GigabitEthernet 2/0/4 belong to VLAN 2 through VLAN 4 respectively, and Host A through Host C
are attached to GigabitEthernet 2/0/2 through GigabitEthernet2/0/4 of Switch A respectively.
z
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.
z
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.

IP
addresses
Configure the IP address and subnet mask for each interface as per
The 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 GigabitEthernet 2/0/2.
