Title : BGP/MPLS Traffic Blackhole Avoidance
Author(s) : R. Asati, et al.
Filename : draft-asati-bgp-mpls-blackhole-avoidance-00.txt
Pages : 16
Date : 2007-2-26
In any BGP based MPLS network such as MPLS VPN [RFC4364], an ingress
PE router would continue to attract traffic from the CE router by
advertising the prefix reachability, even though the Label Switched
Path (LSP) from the ingress PE router to the egress PE router may be
broken. This causes the VPN traffic to be dropped inside the MPLS VPN
network.
This document proposes a framework to make BGP consider the MPLS path
availability to the "NEXT_HOP" (i.e. egress PE router) during the BGP
bestpath candidate selection process. This document also defines a
local database for storing the MPLS path health information for one
or more IP prefixes and its interaction with BGP.

In the body type:

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.
