Applicable Environment
In a metro Ethernet, if a host connected to an interface of the S7700 needs to receive the multicast
flow of a certain multicast group for a long time, you can add the interface to the multicast group.
After static Layer 2 multicast is configured, hosts can receive the multicast flows of the registered
multicast group in a steady and timely manner for a long time. However, in this mode, all the
forwarding entries need to be manually configured. This makes the maintenance difficult, so
this mode is not applicable to a complicated network.
Pre-configuration Tasks
Before configuring static Layer 2 multicast in a VLAN, complete the following tasks:
l Connecting interfaces and configuring the physical parameters of each interface to make
the physical layer in Up state
l Enabling IGMP snooping globally
Data Preparation
To configure static Layer 2 multicast, you need the following data.
No. Data
1 Type and number of the interface that needs
to join a multicast group statically
2 ID of the VLAN that the interface belongs to
3 IP address of the multicast group
2.4.2 Creating a VLAN and Enabling IGMP Snooping
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
vlan vlan-id
A VLAN is created and the VLAN view is displayed.
Step 3 Run:
igmp-snooping enable
The IGMP snooping is enabled in the VLAN.
