In some inter-AS (Autonomous System) and inter-area deployment
scenarios for RFC 4379 ("Label Switched Path (LSP) Ping and
Traceroute"), a replying Label Switching Router (LSR) may not have
the available route to an initiator, and the Echo Reply message sent
to the initiator would be discarded, resulting in false negatives or
a complete failure of operation of the LSP Ping and Traceroute. This
document describes extensions to the 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. This document
updates RFC 4379.
This document is a product of the Multiprotocol Label Switching Working Group of the IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
