1.4.6 Checking the Configuration
Prerequisite
The configuration of static Layer 2 multicast for a VLAN is complete.
Procedure
l Run the display l2-multicast forwarding-table vlan vlan-id [ source-address source-
address ] group-address { group-address | router-group } command to check the
multicast forwarding table of a VLAN.
----End
Example
Run the display l2-multicast forwarding-table vlan 7 command, and you can view the
multicast forwarding table of VLAN 7.
<Quidway> display l2-multicast forwarding-table vlan 7
VLAN ID : 7, Forwarding Mode : IP

1.5.1 Establishing the Configuration Task
Applicable Environment
By configuring multicast VLAN replication, you can manage and control the multicast source
and the multicast group members. In this manner, users in different VLANs can receive the same
multicast flow, and thus bandwidth is saved.
In the implementation of multicast VLAN replication, a VLAN is defined as a multicast VLAN
and the other VLANs are defined as user VLANs. A multicast VLAN is the VLAN that the
interface connecting the S9300 to the multicast source belongs to. The multicast VLAN
converges multicast flows. A user VLAN is the VLAN that interfaces connected to members of
a multicast group belong to. The user VLANs receive the data from the multicast VLAN.
