                   Operations Model for Router Keying
                    draft-ietf-karp-ops-model-08.txt

Abstract

   Developing an operational and management model for routing protocol
   security that works with all the routing protocols will be critical
   to the success of routing protocol security efforts.  This document
   discusses issues and begins to consider development of these models.

Internet-Draft     Operations Model for Router Keying        August 2013

1.  Introduction

   The KARP working group is designing improvements to the cryptographic
   authentication of IETF routing protocols.  These improvements include
   improvements to how integrity functions are handled within each
   protocol as well as designing an automated key management solution.

   This document discusses issues to consider when thinking about the
   operational and management model for KARP.  Each implementation will
   take its own approach to management; this is one area for vendor
   differentiation.  However, it is desirable to have a common baseline
