Abstract Abstract
This document describes methods for performing lsp-ping traceroute This document describes methods for performing lsp-ping traceroute
over mpls tunnels and for traceroute of stitched mpls LSPs. The over mpls tunnels and for traceroute of stitched mpls LSPs. The
techniques outlined in RFC 4379 are insufficient to perform techniques outlined in RFC 4379 are insufficient to perform
traceroute FEC validation and path discovery for a LSP that goes over traceroute FEC validation and path discovery for a LSP that goes over
other mpls tunnels or for a stitched LSP. This document describes other mpls tunnels or for a stitched LSP. This document describes
