Usage Guidelines

Usage Scenario

User-side multicast for a VPN enables a device to identify users of multicast programs in the VPN, thus allowing for refined management of the users. Before configuring user-side multicast for a VPN, run the multicast binding vpn-instance command to bind an interface to the multicast VPN instance. A BAS interface can be bound to multiple multicast VPN instances, and the binding configurations apply to all sub-interfaces of the BAS interface. In this manner, when users send Join messages, the device can identify the VPN information of the users on each sub-interface and forward the messages to the corresponding VPNs. If a user does not belong to any VPN instance configured on the BAS interface, the device drops the multicast messages sent by this user.

Prerequisites

The VPN instance specified in the command has been configured, and multicast routing has been enabled using the multicast routing-enable command for the VPN instance.

Precautions

The multicast binding vpn-instance command can be run for main interfaces, but not for sub-interfaces.

A main interface can be bound to multiple multicast VPN instances.

In VS mode, this command is supported only by the admin VS.

Example

# Bind GE 0/1/0 to the VPN instance named red.

<HUAWEI> system-view
[~HUAWEI] ip vpn-instance red
[*HUAWEI-vpn-instance-red] route-distinguisher 1:1
[*HUAWEI-vpn-instance-red-ipv4] quit
[*HUAWEI-vpn-instance-red] quit
[*HUAWEI] interface GigabitEthernet 0/1/0
[*HUAWEI-GigabitEthernet0/1/0] multicast binding vpn-instance red
