evpn e-tree-leaf

Function

The evpn e-tree-leaf command sets the leaf attribute for an interface.

The undo evpn e-tree-leaf command deletes the leaf attribute of an interface.

By default, the leaf attribute is not set for an interface.

Usage Guidelines

Usage Scenario

In an EVPN E-Tree scenario, if a basic EVPN instance is configured, the EVPN instance is bound to an AC interface. If a BD-EVPN instance is configured, the BD-EVPN instance is bound to a BD, and then the BD is associated with a Layer 2 sub-interface. By default, the AC interface and Layer 2 sub-interface have the root attribute. To set the leaf attribute for the AC interface or Layer 2 sub-interface, run the etree enable and evpn e-tree-leaf commands. This configuration disables leaf AC interfaces from sending traffic to each other. Only a leaf AC interface and a root AC interface can send traffic to each other.

Prerequisites

EVPN E-Tree has been enabled in a BD-EVPN instance or a basic EVPN instance using the etree enable command.

For the basic EVPN instance, the instance has been bound to the target AC interface using the evpn binding vpn-instance command. For the BD-EVPN instance, the target Layer 2 sub-interface has been added to a BD using the bridge-domain command.

Example

# Set the leaf attribute for the AC interface to which an EVPN instance is bound.
