       Label Switched Path (LSP) Ping/Trace Multipath Support for
                Link Aggregation Group (LAG) Interfaces
               draft-akiya-mpls-lsp-ping-lag-multipath-03

Abstract

   This document defines an extension to the Multiprotocol Label
   Switching (MPLS) Label Switched Path (LSP) Ping and Traceroute to
   describe Multipath Information for Link Aggregation (LAG) member
   links separately, thus allowing MPLS LSP Ping and Traceroute to
   discover and exercise specific paths of layer 2 (L2) Equal-Cost
   Multipath (ECMP) over LAG interfaces.

   This document updates RFC4379 and RFC6424.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
