Title : VPLS External Loop Detection and Protection Requirements

Abstract:
Virtual Private LAN Service (VPLS) implementations, as defined in
[RFC4761] and [RFC4762], are highly susceptible to layer-2 loops
external to the PE customer-facing interface. Such loops impact
performance and can have a detrimental affect on all VPLS traffic
throughout the entire instance under certain conditions.
Current Layer-2 loop detection and protection mechanisms do not
function effectively here.
This document describes the requirements for a protocol function
to offer VPLS service providers a mechanism for detecting such
layer-2 loops and facilitating configurable actions without the
need for inter-operation with customer network protocols, other
VPLS PEs or customer sourced frames.
