Title : Advertisement of the Group Best Paths in BGP
Author(s) : E. Chen, N. Chen
Filename : draft-chen-bgp-group-path-update-02.txt
Pages : 14
Date : 2004-9-29
In this document we first identify the (neighbor-AS based) Group Best
Paths for an address prefix as the sufficient subset that can be
advertised by a BGP route reflector or a BGP confederation ASBR to
eliminate the MED-type route oscillations in a network. We then
propose a BGP extension to support the advertisement of the Group
Best Paths by a route reflector or a confederation ASBR. The
extension also allows the advertisement of all the paths in a group
that survive the MED comparison, thus achieving the same routing
consistency as the full IBGP mesh. The proposed mechanisms are
designed such that the vast majority of the BGP speakers in a network
need only minor software changes in order to deploy the mechanisms.

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.
