Usage Guidelines

Usage Scenario

In DCI scenarios, only ES-AD/ES routes carrying VXLAN encapsulation attributes are locally generated by default.

After this command is run in a BD, the device generates VXLAN- and MPLS-encapsulated ES-AD/ES routes, and EVC interfaces added to the BD support split horizon.

Prerequisites

A VNI has been created and associated with a BD using the vxlan vni split-horizon-mode command, and an EVPN instance in BD mode has been bound to the VNI.

Example

# Enable the AC access function.
