In this configuration example, you need to configure the ports that connect Switch A and Switch B to
each other as hybrid ports. The following text describes the configuration details. You can also configure
these ports as trunk ports. The configuration procedure is omitted here. For details, see
Multicast VLAN. Configure a multicast VLAN, so that users in VLAN 2 and VLAN 3 can receive multicast
streams through the multicast VLAN.

Configuration procedure
The following configuration is based on the prerequisite that the devices are properly connected and all
the required IP addresses are already configured.
1) Configure Switch A:
# Set the interface IP address of VLAN 20 to 168.10.1.1 and enable PIM DM on the VLAN interface.
<SwitchA> system-view
[SwitchA] multicast routing-enable
[SwitchA] vlan 20
[SwitchA–vlan20]port GigabitEthernet 1/0/1
[SwitchA-vlan20] quit
[SwitchA] interface Vlan-interface 20

Networking description
VLAN 2 contains GigabitEthernet 1/0/1 and
VLAN 3 contains GigabitEthernet 1/0/2.
The default VLANs of GigabitEthernet 1/0/1 and
GigabitEthernet 1/0/2 are VLAN 2 and VLAN 3
respectively.
VLAN 10 contains GigabitEthernet 1/0/10,
GigabitEthernet 1/0/1, and GigabitEthernet
1/0/2. GigabitEthernet 1/0/10 is connected to
Switch A.
VLAN 10 is a multicast VLAN.
GigabitEthernet 1/0/1 sends untagged packets
for VLAN 2 and VLAN 10.
GigabitEthernet 1/0/2 sends untagged packets
for VLAN 3 and VLAN 10.
Host A is connected to GigabitEthernet 1/0/1 on
Switch B.
Host B is connected to GigabitEthernet 1/0/2 on
Switch B.
