                Advertising Tunneling Capability in OSPF
                  draft-ietf-ospf-encapsulation-cap-04

Abstract

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

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].
