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