Sending a pointer to what I mentioned at the mike on today's meeting:
The group that works on the routing scalability problem at the IRTF is
called Routing Research Group, or RRG. Their web page is here:
http://www.irtf.org/charter?gtype=rg&group=rrg
The mailing list is at rrg(a)psg.com. To subscribe, send mail to
rrg-request(a)psg.com with the word "subscribe" in the body of your email.
This is a quite active group already, but additional participation from
the operator community would be very much appreciated.

Dear All,
During the last ten years, more and more operators have configured their
network with various types of BGP communities that are used for traffic
engineering, blackholing, monitoring and other purposes. A recent survey
of BGP communities in RIPE and RouteViews routing tables
( http://inl.info.ucl.ac.be/publications/bgp-communities )
shows that more than 1000 ASes have defined their own BGP communities
(mostly for traffic engineering purposes ) and half of the BGP routes
carry one or more BGP communities.
These BGP communities are important tools for many operators. However,
they are currently only documented on an adhoc basis, usually either as
notes on web pages or as comments in RPSL specifications. Some BGP
communities may interact in strange ways and debugging those
interactions may be very difficult on the Internet.
We believe that a more precise way of documenting BGP communities would
be useful for both operators and their clients. This method should be
vendor neutral but should allow one to express the policies that are
supported by most router vendors. It should also be possible for a
client to test how one of his route would be filtered by his provider in
function of the BGP communities associated to that route. Doing such
tests in the public Internet is cumbersome and difficult to debug. A
classical example of this difficulty is that some combinations of BGP
communities may lead to BGP wedgies as described in RFC4264.
A better approach would be to have a simulation tool that allows
operators to both define the BGP policies used by their network and also
provide a model that allows their client to test how their routes would
be filtered.
The open-source CBGP simulator ( http://cbgp.info.ucl.ac.be/ ) could be
easily used for this purpose and operators could define a CBGP model of
their network that specifies clearly how routes containing BGP
communities are filtered and give this model to their customers to aid
them to tune their configurations. In the long term, a CBGP model of
each network could be one of the elements of the RPSL specification of a
network.
If you have defined BGP communities in your network and are interested
in developping a BGP model of your network to precisely document the BGP
communities that you use, let us know. We would like to build a set of
reference CBGP models that can be used as best current practices by
other operators.
Best regards,
Olivier Bonaventure and Bruno Quoitin

[routing-wg]2008-04 New Policy Proposal (Using the Resource Public Key Infrastructure to Construct Validated IRR Data)
by Filiz Yilmaz 30 Apr '08

PDP Number: 2008-04
Using the Resource Public Key Infrastructure to Construct Validated IRR Data
Dear Colleagues,
A new RIPE Policy Proposal has been made and is now available for
discussion.
This is a proposal to introduce a new registry that augments IRR
data with the formally verifiable trust model of the Resource Public
Key Infrastructure (RPKI) and provide ISPs with the tools to
generate an overlay to the IRR which is much more strongly
trustable.
You can find the full proposal at:
http://www.ripe.net/ripe/policies/proposals/2008-04.html
We encourage you to review this proposal and send your comments to
<routing-wg(a)ripe.net> before 27 May 2008.
Regards,
Filiz Yilmaz
RIPE NCC
Policy Development Officer
