   OSPF Extensions for Advertising/Signaling Geo Location Information
                  draft-acee-ospf-geo-location-05.txt

Abstract

   This document specifies an OSPF Router Information (RI) TLV to
   advertise the current Geo Coordinates of the OSPF router.  For Point-
   to-Point (P2P)) and Point-to-Multi-Point (P2MP) networks, the Geo
   Coordinates can be used to dynamically computing the cost to
   neighbors.  This is useful both from the standpoint of auto-
   configuration and situations where the OSPF routers are moving.  The
   Geo Coordinates are also useful for other applications such as
   Traffic Engineering (TE) and network management.

1.  Introduction

   This document specifies an OSPF Router Information (RI) [OSPF-RI] TLV
   to advertise the current Geo Coordinates of the OSPF router.  For
   Point-to-Point (P2P)) and Point-to-Multi-Point (P2MP) networks, the
   Geo Coordinates can be used to dynamically computing the cost to
   neighbors.  This is useful both from the standpoint of auto-
   configuration and situations where the OSPF routers are moving.  The
   Geo Coordinates are also useful for other applications such as
   Traffic Engineering (TE)and network management.

1.1.  Requirements Notation

   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-KEYWORDS].

2.  OSPF Geo Coordinates TLV

   The Geo Coordinates TLV can be used to advertise the current location
   of an OSPFv2 [OSPF] or OSPFv3 [OSPFV3] router using the OSPF Router
   Information LSA [OSPF-RI].  The OSPF Router Information LSA can be
   advertised in both link-scoped and area or AS scoped RI LSAs.  The
   fields specify the location of the OSPF router using the WGS-84
   (World Geodetic System) reference coordinate system [WGS84].  The
   value of the Geo Coordinates TLV consists of the following fields:
