Abstract:

   The MPLS echo request and MPLS echo response messages, defined in RFC
   8029 "Detecting Multiprotocol Label Switched (MPLS) Data-Plane
   Failures" (usually referred to as LSP ping messages), are
   encapsulated in IP headers that include a Router Alert Option (RAO).
   The rationale for using an RAO as the exception mechanism is
   questionable.  Furthermore, RFC 6398 identifies security
   vulnerabilities associated with the RAO in non-controlled
   environments, e.g., the case of using the MPLS echo request/reply as
   inter-area Operations, Administration, and Maintenance (OAM), and
   recommends against its use outside of controlled environments.

   Therefore, this document retires the RAO for MPLS OAM and updates RFC
   8029 to remove the RAO from LSP ping message encapsulations.
   Furthermore, this document explains why RFC 7506 has been
   reclassified as Historic.

   This document also recommends the use of an IPv6 loopback address
   (::1/128) and not the use of an IPv4 loopback address mapped to IPv6.
