| Parameter | Description | Value |
|---|---|---|
| vpn-instance-name |
Binds an interface to a specified VPN instance. |
The value is a string of 1 to 31 case-sensitive characters, spaces not supported. In addition, the VPN instance name must not be _public_. When double quotation marks are used around the string, spaces are allowed in the string. |
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 ipv6 binding vpn-instance command to bind an interface to the multicast VPN instance. 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.
Prerequisites
The VPN instance specified in the command has been configured, and multicast routing has been enabled using the multicast ipv6 routing-enable command for the VPN instance.
Precautions
An interface can be bound to multiple multicast VPN instances.
In VS mode, this command is supported only by the admin VS.
