l2 binding e-tree leaf

Function

The l2 binding e-tree leaf command configures the leaf attribute for an AC interface.

The undo l2 binding e-tree leaf command restores the default attribute of an AC interface.

By default, the attribute of an AC interface is root.

Usage Guidelines

Usage Scenario

In a VPLS domain, AC interfaces bound to the same VSI can communicate with each other. To enhance data security and minimize mutual influences between users, controlling communication between these AC interfaces is required. VPLS E-Tree can meet this requirement by allowing you to configure the root or leaf attribute for AC interfaces. A root AC interface can communicate with leaf AC interfaces and other root AC interfaces, while a leaf AC interface can communicate only with root AC interfaces.

To specify the leaf attribute for an AC interface, run the l2 binding e-tree leaf command.

Prerequisites

The following commands have been configured:

The e-tree static command has been configured to enable the VPLS E-Tree function.
The l2 binding vsi vsi-name [ access-port ] command has been configured to bind an AC interface to a VSI.

Example

# Specify the AC interface of a VSI as a leaf.
