Abstract

   This document describes a mechanism to enable using IKEv2 with TCP-
   AO, which may also be of more general use to other pairwise Routing
   Protocols.

1.  Introduction

   This document analyzes the pairwise Routing Protocol (RP)
   requirements needed to integrate the IKEv2[RFC5996] KMP and provides
   a framework to achieve this.

   The KARP design guide [RFC6518] suggests various requirements and
   options for obtaining keys to protect the routing protocols and
   recommends using a Key Management Protocol (KMP) to automate key
   establishment, as well as rekeying to continuously protect the
   routing protocols.  However, there are few gaps which need to be
   addressed for serene integration of IKEv2 KMP and any pairwise
   routing protocol either securing messages by RP itself or through a
   security protocol like TCP-AO [RFC5925].  For example, there are
   differences in both established protocols like IKEv2 and TCP-AO on
   how the Security Associations (SAs) to be maintained or there is a
   need for common framework in general on how the pairwise RPs can
