Abstract

   This memo specifies, for OSPF implementors and users, mechanisms
   describing how the protocol operates in ATM networks over PVC and SVC
   meshes with the presence of Proxy-PAR. These recommendations require
   no protocol changes and allow simpler, more efficient and cost-
   effective network designs. It is recommended that OSPF
   implementations should be able to support logical interfaces, each
   consisting of one or more virtual circuits and used either as
   numbered logical point-to-point links (one VC), logical NBMA networks
   (more than one VC) or Point-to-MultiPoint networks (more than one
   VC), where a solution simulating broadcast interfaces is not
   appropriate. PAR can help distribute across the ATM cloud
   configuration setup and changes of such interfaces when OSPF capable
   routers are (re-)configured.  Proxy-PAR can in turn be used to
   exchange this information between the ATM cloud and the routers
   connected to it.

1 Introduction

   Proxy-PAR and PAR have been accepted as standards by the ATM Forum in
   January 1999 [1]. A more complete overview of Proxy-PAR than in the
   section below is given in [2].
