Unlike Open Shortest Path First version 2 (OSPFv2) [RFC2328], OSPF for IPv6 (OSPFv3) [RFC5340] does not include the AuType and Authentication fields in its headers for authenticating protocol packets. Instead, OSPFv3 relies on the IPsec protocols Authentication Header (AH) [RFC4302] and Encapsulating Security Payload (ESP) [RFC4303] to provide integrity, authentication, and/or confidentiality.

               Supporting Authentication Trailer for OSPFv3


   Currently, OSPF for IPv6 (OSPFv3) uses IPsec as the only mechanism    for authenticating protocol packets.  This behavior is different from    authentication mechanisms present in other routing protocols (OSPFv2,    Intermediate System to Intermediate System (IS-IS), RIP, and Routing    Information Protocol Next Generation (RIPng)).  In some environments,    it has been found that IPsec is difficult to configure and maintain    and thus cannot be used.  This document defines an alternative    mechanism to authenticate OSPFv3 protocol packets so that OSPFv3 does    not depend only upon IPsec for authentication.

   The OSPFv3 Authentication Trailer was originally defined in RFC 6506.    This document obsoletes RFC 6506 by providing a revised definition,    including clarifications and refinements of the procedures.
