                          OSPF Two-part Metric
                 draft-ietf-ospf-two-part-metric-05.txt

Abstract

   This document specifies an optional extension to the OSPF protocol,
   to represent the metric on a multi-access network as two parts: the
   metric from a router to the network, and the metric from the network
   to the router.  The router to router metric would be the sum of the
   two.  This document updates RFC 2328 and RFC 5340.

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 [RFC2119].
