Extended Ping (Xping)
draft-bonica-intarea-eping-04
Abstract
This document describes a new diagnostic tool called Extended Ping
(Xping). Network operators execute Xping to determine the status of
a remote interface. In this respect, Xping is similar to Ping.
Xping differs from Ping in that it does not require network
reachability between itself and remote interface whose status is
being queried.
Xping relies on two new ICMP messages, called Extended Echo Request
and Extended Echo Reply. Both ICMP messages are defined herein.
Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].

1. Problem Statement
Network operators use Ping [RFC2151] to determine whether a remote
interface is operational. Ping sends an ICMP [RFC0792] [RFC4443]
Echo message to the interface being probed and waits for an ICMP Echo
Reply. If Ping receives the expected ICMP Echo Reply, it reports
