Figure 6: Layer 2 External Connectivity with a VPLS Network Through an Access VFI Note We recommend you to use Cisco Catalyst 9500 Series - High Performance switches or Cisco Catalyst 9600 Series switches as border VTEPs when you configure Layer 2 external connectivity with a VPLS network. We recommend you to configure Cisco StackWise Virtual on the border VTEPs in order to achieve physical redundancy when you configure Layer 2 external connectivity with a VPLS network. Perform the following set of procedures to enable Layer 2 external connectivity with VPLS networks through an access VFI interface: 1. Define the access VFI for the VTEPs. 2.
Configure the access VFI as a member of the VLAN on the VTEPs. 3. Configure the EVPN instance as a member of the VLAN on the VTEPs. 4. Configure VPLS on the border VTEP. Defining an Access VFI on a Border VTEP To configure an access facing VFI on the VLAN of a border VTEP, perform the following steps: For more information on configuring VFIs, in the software configuration guide for the required release, go to Contents Multiprotocol Label Switching (MPLS) Configuration Guide Configuring Virtual Private LAN Service (VPLS) and VPLS BGP-Based Autodiscovery .
