Abstract

   This document describes a mechanism to secure pairwise Routing
   Protocol associations using the IKEv2 Key Management Protocol (KMP).
   Most of the pairwise Routing Protocols (RPs) are TCP-based but the
   framework described here is applicable to other pairwise RPs, which
   not necessarily use the TCP at transport layer.  A Gatekeeper
   mechanism is introduced to allow all pairwise RPs to coordinate with
   IKEv2 Protocol to pass the policy, get the keying material and to
   maintain the security associations.  The Gatekeeper also allows
   pairwise RPs which use TCP-AO to coordinate with IKEv2 without
   fundamental modification to either.

1.  Introduction

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

   The KARP design guide [RFC6518] suggests various requirements and
