Abstract

   This document specifies requirements for a generic route-tracing
   application.  It also specifies requirements for a protocol that will
   support that application.  Network operators will use the generic
   route-tracing application to verify proper operation of the IP
   forwarding plane.  They will also use the application to discover
   details regarding tunnels that support IP forwarding.

   The generic route-tracing application, specified herein, supports a
   superset of the functionality that "traceroute" currently offers.
   Like traceroute, the generic route-tracing application can discover
   the forwarding path between two interfaces that are contained by an
   IP network.  Unlike traceroute, this application can reveal details
   regarding tunnels that support the IP forwarding path.

1.  Introduction

   IP networks utilize several tunneling technologies.  Although these
   tunneling technologies provide operators with many useful features,
   they also present management challenges.  Network operators require a
   generic route-tracing application that they can use to verify the
   correct operation of the IP forwarding plane.  The generic
   route-tracing application must be capable of detecting tunnels and
   revealing tunnel details.  The application also must be useful in
   diagnosing tunnel faults.
