Abstract Abstract
In some inter-AS and inter-area deployment scenarios for LSP Ping and 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 Traceroute, a replying LSR may not have the available route to the
initiator, and the Echo Reply message sent to the initiator would be initiator, and the Echo Reply message sent to the initiator would be
discarded resulting in false negatives or complete failure of discarded resulting in false negatives or complete failure of
operation of LSP Ping and Traceroute. This document describes operation of LSP Ping and Traceroute. This document describes
extensions to LSP Ping mechanism to enable the replying LSR to have extensions to LSP Ping mechanism to enable the replying LSR to have
the capability to relay the echo response by a set of routable the capability to relay the echo response by a set of routable
