Abstract

   This memo defines how ILMI-based Server Discovery, which provides a
   method for ATM-attached hosts and routers to dynamically determine
   the ATM addresses of servers, shall be used to locate NHRP servers.

1. Introduction

   Presently, configuring a host or router to use NHRP [1] is cumbersome
   and error-prone since it requires at least one ATM address to be
   statically configured on each host or router in the network.
   Further, it is impossible to implement a diskless host to use NHRP
   since local configuration is required.  ILMI-based Server Discovery,
   hereafter referred to as "server discovery," provides a solution to
   these problems.

   A brief overview of the Integrated Local Management Interface (ILMI)
   and the Service Registry MIB, as defined by the ATM Forum, are
   provided in this memo. The reader should consult [2] for a complete
   description of ILMI and this MIB, but the information contained here
   is sufficient for an understanding of its use to support NHRP server
   discovery.

2. Integrated Local Management Interface

   The Integrated Local Management Interface (ILMI) [2] provides a
   mechanism for ATM-attached devices, such as hosts, routers, and ATM
   switches, to transfer management information. It is based on the
   Simple Network Management Protocol (SNMP), Version 1, and supports
