This document describes methods for performing lsp-ping traceroute over mpls tunnels. The techniques outlined in RFC 4379 fail to perform correct traceroute validation and path discovery for a LSP that goes over other mpls tunnels. This document describes new procedures that can be used in conjunction with the standard procedures described in RFC 4379 to trace such LSPs.
