Title : VPLS external Loop Protection Mechanism (VLPM)

Abstract:
Virtual Private LAN Service (VPLS) as defined in RFC4761 [RFC4761]
and RFC4762 [RFC4762] implementations are highly susceptible to
layer-2 loops external to the PE customer-facing interface. Such
loops impact performance and can have a detrimental effect on all
VPLS traffic throughout the entire instance under certain
conditions.
Current Layer-2 loop protection and protection mechanisms do not
function effectively here.
This document describes a protocol function (VPLS External Loop
Protection Mechanism (VLPM)) 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 sites.
