PROBE: A Utility for Probing Interfaces
Abstract
This document describes a network diagnostic tool called PROBE.
PROBE is similar to PING in that it can be used to query the status
of a probed interface, but it differs from PING in that it does not
require bidirectional connectivity between the probing and probed
interfaces. Instead, PROBE requires bidirectional connectivity
between the probing interface and a proxy interface. The proxy
interface can reside on the same node as the probed interface, or it
can reside on a node to which the probed interface is directly
connected. This document updates RFC 4884.

RFC 8335 PROBE February 2018
1. Introduction
Network operators use PING [RFC2151] to test bidirectional
connectivity between two interfaces. For the purposes of this
document, these interfaces are called the probing and probed
interfaces. PING sends an ICMP [RFC792] [RFC4443] Echo Request
message from the probing interface to the probed interface. The
probing interface resides on a probing node while the probed
interface resides on a probed node.
If the probed interface receives the ICMP Echo Request message, it
returns an ICMP Echo Reply. When the probing interface receives the
ICMP Echo Reply, it has verified bidirectional connectivity between
