Abstract:
   The echo request and echo response messages, defined in RFC 8029
   "Detecting Multiprotocol Label Switched (MPLS) Data-Plane Failures"
   (aka LSP ping messages), are encapsulated in IP headers that include
   a Router Alert Option (RAO).  The rationale for having an RAO is
   questionable.  Furthermore, RFC 6398 identifies security
   vulnerabilities associated with the RAO.

   Therefore, this document removes the RAO from LSP ping message
   encapsulations.  It updates RFCs 7506 and 8029.

   This document also recommends the use of an IPv6 loopback address
   (::1/128) and discourages the use of an IPv4 loopback address mapped
   to IPv6.
