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').

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').

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').

Dear Colleagues
The RIPE NCC Training Services Department invites you to register for one
of our upcoming Routing Registry Training Courses:
Date: Friday 10 March 2006
Time: 0900 - 1700
Location: Kiev, Ukraine
Hosted by: Hosted by EDU Incom
And
Date: Tuesday 11 April 2006
Time: 0900 - 1700
Location: London, United Kingdom
And
Date: Friday 5 May 2006
Time: 0900 - 1700
Location: Valletta, Malta
And
Date: Friday 12 May 2006
Time: 0900 - 1700
Location: Amsterdam, Netherlands
And
Date: Friday 19 May 2006
Time: 0900 - 1700
Location: Moscow, Russian Federation
The main objective of the "Routing Registry Training Course" is to
familiarise the LIRs with the features of the Routing Registry, while
introducing the relevant tools and services of the RIPE NCC.
The course also offers practical exercises.
OVERVIEW OF TOPICS COVERED IN THE COURSE:
- Routing Registry as a part of the RIPE Whois Database and the
Internet Routing Registry (IRR)
- Specifying routing policies using (RPSL)
Routing Policy Specification Language and the RtConfig tool
- IRRToolSet
- Routing Information Service (RIS)
- Routing Registry Consistency Check Project
Please note that this is an advanced course. It will:
- NOT teach the basics of routing
- NOT teach the basics of RIPE Database operations
- NOT describe how to receive Internet resources from the RIPE NCC
- NOT describe how to operate a Local Internet Registry (LIR)
The target audience of the course are technical staff of LIRs: e.g.
network operators, engineers etc. This course is not intended for
administrative or management staff (e.g. Hostmasters) .
It is assumed that all attendees will be familiar with
Border Gateway Protocol routing and with the RIPE Database
(i.e. creating/modifying objects).
This course is based on interactive exercises in a local network set-up.
Please bring your laptops equipped with the following:
- A working Ethernet card,
- Three meters of Ethernet cable,
- A secure connection client,
- A web browser.
Please be prepared to share your laptop (or at least allow another
attendee to "look over your shoulder") if necessary.
The course is free of charge. We provide lunch and printed training materials.
We do not cover any of your travel expenses or accommodation.
We give all of our training courses in English.
You can find more information about the course at:
http://www.ripe.net/training/rr/
How to register:
---------------------
You can register up to two people from your LIR for each course.
(If there are places left nearer the time of the course, you can register more people).
To register for this course, you can either use the LIR Portal at:
https://lirportal.ripe.net/lirportal/training/course-list.html
Or the online registration form on our website:
http://www.ripe.net/cgi-bin/trainingform.pl.cgi
If you have any questions, send an e-mail to <training(a)ripe.net>.
Kind regards,
Rumy Kanis
Training Services Manager

Just wanted to drop a short to let everyone know that
we did fix the annoying bug that was causing the
bgpinspect global summary statistics to be zeroes(or
inaccurate). These should be working correctly now.
I would recommend that people periodically check out
the top20 lists. If your AS suddently shows up there in
terms of activity, there might be some inherent problem
that is responsible for the instability.
The "Most Origin AS changes" query results should be
taken with a grain of salt, this currently does not
correctly account for MOAS behaviour.

Dear All,
C-BGP is an efficient and open-source simulation tool that allows to
simulate the behavior of the intra- and interdomain routing protocols in
large ISP networks. C-BGP is able to simulate networks with thousands of
routers. A key feature ofco C-BGP compared to other simulators is that
it is able to support the complex routing policies that are used by ISPs.
Thanks to the support of France Telecom R&D, we have been able to use
C-BGP to reproduce the behavior of BGP in a large Tier-1 ISP network.
For this analysis, we have developped several tools to automatically
convert the BGP configurations of Juniper (JUNOS) and Cisco (IOS)
routers, the IGP topology and the BGP routes in the C-BGP format. With
these tools, any network operator can easily build a C-BGP model of
his/her network. With such a model, it is possible to perform different
types of analysis on the ISP network, such as :
- predicting the flow of the traffic through the network or
determining the traffic matrix based on Netflow data (see article in
January issue of ACM SIGCOMM Computer Communication Review)
- predicting the impact of adding a new peering link on the BGP routes
selected by the routers (see article in Nov/Dec issue of IEEE Network
Magazine)
- predicting the impact of link or router failures on the ISP network
You can obtain C-BGP, the conversion tools and several papers describing
the utilization of C-BGP to model an ISP network or compute traffic
matrices from :
http://cbgp.info.ucl.ac.be
The website also contains several examples, such as a complete C-BGP
model of the Abilene Network based on their publically available JUNOS
configurations files.
We believe that C-BGP could be very useful for ISPs willing to optimise
the distribution and the selection of the BGP routes in their network.
Comments, suggestions and questions from network operators are more than
welcome.
Best regards,
Bruno Quoitin, Sebastien Tandel and Olivier Bonaventure
