--Boundary_(ID_7WgSXfH+VQuKE2jHxl+2iQ) Content-type: TEXT/PLAIN Content-transfer-encoding: 7BIT A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : Route Reflection Considered Harmful Author(s) : R. Dube, J. Scudder Filename : draft-dube-route-reflection-harmful-00.txt Pages : 5 Date : 04-Nov-98 Route reflection as defined by [2] is a popular way of reducing the full-mesh IBGP peering required by routers running the Border Gateway Protocol [1]. There are cases where a topology built using route reflectors produces persistent loops or does not produce the same results as what one would expect with a full IBGP mesh. This document describes these problems. Internet-Drafts are available by anonymous FTP. Login with the username "anonymous" and a password of your e-mail address. After logging in, type "cd internet-drafts" and then "get draft-dube-route-reflection-harmful-00.txt". A URL for the Internet-Draft is: ftp://ftp.ietf.org/internet-drafts/draft-dube-route-reflection-harmful-00.txt Internet-Drafts directories are located at: Africa: ftp.is.co.za Europe: ftp.nordu.net ftp.nis.garr.it Pacific Rim: munnari.oz.au US East Coast: ftp.ietf.org US West Coast: ftp.isi.edu Internet-Drafts are also available by mail. Send a message to: mailserv@ietf.org. In the body type: "FILE /internet-drafts/draft-dube-route-reflection-harmful-00.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. --Boundary_(ID_7WgSXfH+VQuKE2jHxl+2iQ) Content-type: MULTIPART/ALTERNATIVE; BOUNDARY="Boundary_(ID_i1xvPY+rYZXJ++688kA3BQ)" --Boundary_(ID_i1xvPY+rYZXJ++688kA3BQ) Content-type: Message/External-body; access-type="mail-server"; server="mailserv@ietf.org" Content-Type: text/plain Content-ID: <19981104173505.I-D@ietf.org> ENCODING mime FILE /internet-drafts/draft-dube-route-reflection-harmful-00.txt --Boundary_(ID_i1xvPY+rYZXJ++688kA3BQ) Content-type: Message/External-body; directory=internet-drafts; access-type=anon-ftp; site=ftp.ietf.org; name=draft-dube-route-reflection-harmful-00.txt Content-disposition: ATTACHMENT; FILENAME=draft-dube-route-reflection-harmful-00.txt Content-Type: text/plain Content-ID: <19981104173505.I-D@ietf.org> --Boundary_(ID_i1xvPY+rYZXJ++688kA3BQ)-- --Boundary_(ID_7WgSXfH+VQuKE2jHxl+2iQ)-- ----- End Included Message -----
