Abstract:
The widespread adoption of Ethernet L2VPN services and the advent of
new applications for the technology (e.g., data center interconnect)
have culminated in a new set of requirements that are not readily
addressable by the current Virtual Private LAN Service (VPLS)
solution. In particular, multi-homing with all-active forwarding is
not supported and there's no existing solution to leverage
Multipoint-to-Multipoint (MP2MP) LSPs for optimizing the delivery of
multi-destination frames. Furthermore, the provisioning of VPLS, even
in the context of BGP-based auto-discovery, requires network
operators to specify various network parameters on top of the access
configuration. This document specifies the requirements for an
Ethernet VPN (EVPN) solution which addresses the above issues.
