Abstract:
   In some inter-AS and inter-area deployment scenarios for LSP Ping and
   Traceroute, a replying LSR may not have the 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 LSR to have
   the capability to relay the echo response by a set of routable
   intermediate nodes to the initiator during the traceroute process in
   inter-AS and inter-area scenarios.
