RFC 8335: PROBE: A Utility for Probing Interfaces
Recent RFCs 2018-02-22
Summary:
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.
