Technical Summary
This document describes the ICMPv6 Reflection utility. The ICMPv6
Reflection utility is a diagnostic tool, similar to Ping and the
ICMPv6 Probe utility. It is similar to Ping and Probe in that it
relies on a stateless message exchange between a probing node and a
probed node. The probing node sends a request to the probed node and
the probed node responds to the request.
The ICMPv6 Reflection utility differs from Ping and Probe because, in
the ICMPv6 Reflection utility, the probing node requests a snapshot
of the message that it sent, as it was when arrived at the probed
node. The probed node returns the requested snapshot.
The ICMPv6 Reflection utility is useful because it can allow the user
to see how the network modified the request as it traveled from the
probing node to the probed node.
