Ethernet VPN Virtual Private Wire Service
EVPN VPWS (Ethernet VPN Virtual Private Wire Service) is a BGP control plane solution for point-to-point
services. It implements signaling and encapsulation techniques for establishing an EVPN instance between a
pair of provider edge devices.
EVPN VPWS supports both single-homing and multi-homing.
Configuration
The following sections describes the procedure for configuring IP Fast Reroute with Remote LFA.
• Configure L2VPN on the provide edge router
• Configure BFD on the customer edge router
Configure L2VPN on the Provide Edge Router
Configure L2VPN on the provider edge router.
