Usage Guidelines

Usage Scenario

Before configuring groups for a channel, you need to define a name for the channel. The channel command can be used to set a name for a channel and select the model (ASM or SSM) of multicast group addresses.

Precautions

The names of a global channel, and a channel in a VSI cannot be the same.

Example

# Configure a global channel named a1.

<HUAWEI> system-view
[~HUAWEI] l2-multicast-channel
[*HUAWEI-l2-channel-glb] channel a1 type asm

# Configure a channel named c1 in VSI vpna.

<HUAWEI> system-view
[~HUAWEI] mpls
[*HUAWEI-mpls] quit
[*HUAWEI] mpls l2vpn
[*HUAWEI-l2vpn] quit
[*HUAWEI] vsi vpna
[*HUAWEI-vsi-vpna] pwsignal ldp
[*HUAWEI-vsi-vpna-ldp] vsi-id 1
[*HUAWEI-vsi-vpna-ldp] quit
[*HUAWEI-vsi-vpna] quit
[*HUAWEI] l2-multicast-channel vsi vpna
