Hi,
our announcement on nanog a few months ago of experiments involving BGP
updates containing large AS-sets [1] caused a few flames. Now we have an
in-depth document with results on the subject and would like to explain
what we intended to do.
We have presented our techniques at RIPE 50, and there is a Web page on
the project, with links to the full report and the slides, up at:
http://www.dia.uniroma3.it/~compunet/bgp-probing/
What follows is a brief summary of what we do, why we believe it is
safe, and why it shouldn't cause problems to current operational
practices. For more details, see the presentation and the report.
We will be happy to answer any further questions you might have.
Regards,
Lorenzo Colitti

Active BGP Probing
==================
What we do
----------
Existing topology discovery techniques are good at discovering topology
but bad at discovering policy. However, to predict the effect of network
faults, perform effective traffic engineering, develop peering
strategies, and evaluate the quality of upstreams, it would be useful
for ISPs to to know how their announcements can be propagated and how
the policies of other ASes in the Internet affect their prefixes. No
operational tools exist to do this.
The principle is the following: an AS using our probing techniques can
announce one of its prefixes with AS-paths including the numbers of
other ASes. Due to loop detection, these "prohibited" ASes will not use
or propagate the announcement. To avoid influencing AS-path length, the
prohibited ASes are placed in an AS-set at the end of the path.
Thus, to stop its announcement from being propagated by ASes 1, 2, and
3, an AS (say AS12654) might announce one of its prefixes with an
AS-path of 12654 {1,2,3}. This allows AS 12654 to discover who
propagates its announcements, find backup paths, and deduce the policies
of other ASes with respect to its prefixes.
To collect data it is possible to the RIS or ORV route collectors.
However, since our methods operate in steady state, the results are
visible from any looking glass on the Internet.
Why it is safe
--------------
We are confident that such announcements are safe, provided that the
length of the AS-set announced is limited. We say this based on:
1. Equipment tests. Juniper routers seem to have no problems with long
AS-paths, while Cisco routers reset the BGP session when the AS-path
more than 512 bytes long (about 254 ASes). Cisco is aware of this issue
and is in the process of fixing it; in any case, our techniques limit
the length of the AS-sets announced to a suitable number to account for
propagation (obviously, much smaller than 254).
2. IPv6 tests. We started testing our techniques on the IPv6 backbone in
November. No problems were reported. The first report (of only two) we
got of someone even noticing the unusually long paths arrived at the end
of February.
3. Observation. Longer AS-sets (123 [2] and 124 [3] elements) and longer
AS-paths have been observed in the wild with no ill effects that we know
of -- at least, we know of no operators who reported problems.
Why it doesn't impact routers
-----------------------------
Route flap dampening limits our probing to the order of one update per
hour. This is negligible compared to the over 15,000 updates/hour a
typical Tier-1 router might receive. As regards impact on memory, the
amount of RAM to store a 100-element AS-set for one prefix is of the
order of hundreds of bytes, which is irrelevant for core routers which
are already using tens of megabytes of memory for BGP.
Why it doesn't hamper debugging
-------------------------------
Prepending other AS numbers is to a certain extent already done today.
Our techniques are similar, but foreign ASes are only in the AS-set at
the end of the path, so it's immediately obvious which path the
announcement has taken. Due to the size of the AS-set, we doubt that
anyone seeing such an announcement would believe it was due to one of
the ASes in the set, but would probably look at the first AS before the
set. Furthermore, the prefix immediately identifies the source of the
announcements. Finally, the routes can also be tagged with communities
to help identify them.

so...
randy poked, some private nudging (and you know who you are!)
leads me to make this plea...
if a couple of transit providers and perhaps an end site or
two, who would like to participate in a quasi-persistant
trial run of a non-real-time hack to be able to "spray" the
prefixes they inject into the routing system with their
origin AS and public key "scent" ... and provide haqs^^^ooks
to allow random third parties to check the same, please
send me private email and i think we can cobble something
together in a fairly short period. we might even be able to
have several months/weeks/days of emperical data to review
analysis before the next conflab. takers?

Aggregation Summary
The algorithm used in this report proposes aggregation only
when there is a precise match using the AS path, so as
to preserve traffic transit policies. Aggregation is also
proposed across non-advertised address space ('holes').

Hi,
currently, we have both the CIDR Report and APNIC's weekly routing table
report being posted here on the routing-wg list. The CIDR report is
also posted to the EOF list.
Given that both reports are somewhat operational stuff, I think that
both belong to the EOF list (as "equivalent" of NANOG, AFNOG etc.),
but not too much to the routing-wg list.
My suggestion would be to ask Geoff to cease posting to routing-wg
(but keep eof-list) and ask APNIC to post to EOF-list instead.
How do people feel about that? Does that make sense?
Best regards,
Daniel
