A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Internetworking Over NBMA Working Group of the IETF. Title : NHRP for Destinations off the NBMA Subnetwork Author(s) : Y. Rekhter, J. Halpern Filename : draft-ietf-ion-r2r-nhrp-03.txt Pages : 15 Date : 24-May-99 The NBMA Next Hop Resolution Protocol (NHRP) [1] specifies a mechanism that allows a source station (e.g., a host or a router) on an NBMA subnetwork to find the NBMA subnetwork address address of a destination station when the destination station is connected to the NBMA subnetwork. For the case where the destination station is off the NBMA subnetwork the mechanism described in [1] allows to determine the NBMA subnetwork address of an egress router from the NBMA subnetwork that is 'nearest' to the destination station. If used to locate an egress router wherein the destination station is directly behind the egress router, the currently document NHRP behaviors are sufficient. However, as documented elsewhere [2], there are cases where if used between routers for generalized transit, NHRP can produce loops. This document describes extensions to the NBMA Next Hop Resolution Protocol (NHRP) [1] that allow to acquire and maintain the information about the egress router without constraining the destination(s) to be directly connected to the egress router.

A list of Internet-Drafts directories can be found in http://www.ietf.org/shadow.html or ftp://ftp.ietf.org/ietf/1shadow-sites.txt Internet-Drafts can also be obtained by e-mail. Send a message to: mailserv@ietf.org. In the body type: "FILE /internet-drafts/draft-ietf-ion-r2r-nhrp-03.txt". NOTE: The mail server at ietf.org can return the document in MIME-encoded form by using the "mpack" utility. To use this feature, insert the command "ENCODING mime" before the "FILE" command. To decode the response(s), you will need "munpack" or a MIME-compliant mail reader. Different MIME-compliant mail readers exhibit different behavior, especially when dealing with "multipart" MIME messages (i.e. documents which have been split up into multiple messages), so check your local documentation on how to manipulate these messages. Below is the data which will enable a MIME compliant mail reader implementation to automatically retrieve the ASCII version of the Internet-Draft.
