Technical Summary
In some inter autonomous system (AS) and inter-area deployment
scenarios for RFC 4379 "Label Switched Path (LSP) Ping and
Traceroute", a replying LSR might not have an available route to the
initiator, and the Echo Reply message sent to the initiator would be
discarded resulting in false negatives or complete failure of
operation of LSP Ping and Traceroute. This document describes
extensions to LSP Ping mechanism to enable the replying Label
Switching Router (LSR) to have the capability to relay the Echo
Response by a set of routable intermediate nodes to the initiator.
This document updates RFC 4379 by adding those extensions.
