           The Tunnel Encapsulations OSPF Router Information
                  draft-ietf-ospf-encapsulation-cap-09

Abstract

   Networks use tunnels for a variety of reasons.  A large variety of
   tunnel types are defined and the tunnel encapsulator router needs to
   select a type of tunnel which is supported by the tunnel decapsulator
   router.  This document defines how to advertise, in OSPF Router
   Information Link State Advertisement (LSAs), the list of tunnel
   encapsulations supported by the tunnel decapsulator.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].
