New Routing Arbiter Tools Announce
----------------------------------
The Routing Arbiter welcomes comments, bug-reports and suggestions
for new tools. Please direct email to ra-team@ra.net.
Please feel free to redistribute this announcement.

Online Tools and Reports
------------------------
IRRWeb
This graphical interface into the Internet Routing Registry makes
it possible to use the Web to query the IRR and update RADB AS
objects, Route objects, and Maintainer objects. Users can enter
any value that can be submitted through a whois query, such as an
AS number, network IP address, or maintainer. IRRWeb then displays
the corresponding AS objects, Route objects, or Maintainer objects
from the various registries in the IRR. Authorized maintainers can
edit the objects directly; IRRWeb performs a cursory pre-check and
mails the revised object to auto-dbm@ra.net. The user then
receives e-mail from auto-dbm confirming and displaying the revised
object, or explaining why the object was rejected.

Daily NAP Route Flap Reports</A>
This new tool set generates daily reports of route flaps (link
failures at regular and short intervals) throughout the Internet.
Modeled after the reports originally produced by Curtis Villamizar
of ANS, the new reports are generated using tools packaged with
Merit's Multi-Threaded Routing Toolkit. The data is obtained from
peering sessions with Route Servers at the interconnection points.
The reports note the last state of the route (up or down), the
length of time that a route existed (or did not exist) for that
prefix, and the number of times a route for the prefix transitioned
from down to up, up to down, or was replaced by a new route with
changed attribute information. AS-path-specific information is
also provided for every path announced for the prefix.
See http://www.ra.net/~ra/tools/flap.html
Route History Server
The Route History Server provides a mechanism for tracking
the announce/withdraw history of a given prefix for the last 24
hours. The History Server peers with the route servers at
each NAP and records all BGP updates in History Server/Route
Server peering session.
See http://www.ra.net/cgi-bin/ra/rshist.pl

Tools Available for FTP
-----------------------
RSd
The Route Server daemon (RSd) is an enhanced version of
the GateD routing software that provides multiples views of
routing information.
The software provides a mechanism for network service provides
to off-load the computational complexity of routing policy
calculations from their routers. RSd supports configuration and
transparent passing of BGP MEDs. The software also supports
BGP route flap dampening.
Available at ftp://ftp.ra.net/routing.arbiter/tools/rsd.tar.gz
Peval
A policy evaluator that inputs a RIPE-181 policy
expression, performs essential background
calculations such as symbolic evaluations and
expansions, and outputs another RIPE-181 policy
expression that is used by other tools, such as
RTConfig.
Available as part of the RAToolSet at
ftp://ftp.ra.net/routing.arbiter/tools/RAToolSet
RTConfig
A router configuration tool that can be used by
providers to generate router configs directly from
the RADB or other IRR registries. Currently in
production use for the RA Route Servers, ANSNET, and
CA*net, RTConfig is a front-end tool that uses peval
and radbserver transparently to users.
Available as part of the RAToolSet at
ftp://ftp.ra.net/routing.arbiter/tools/RAToolSet
rrc2r/rrmerge
This Cisco-to-RIPE-181 conversion package makes it possible for
users to convert Cisco router configuration files to RIPE-181
objects that can be submitted to the Internet Routing Registry
(IRR). The Cisco access-list can be converted into an explicit set
of nets embedded in an AS object or represented as a community.
The RADBserver is queried for any missing or previously registered
information.
Available at
ftp://ftp.ra.net/routing.arbiter/tools/RAToolSet/rrc2r-0.2.tar.gz
CiscoBGP
IRR users have long recognized the need for tools that check the
IRR against routes actually propagated in the Internet. CiscoBGP
obtains and analyzes routing information from production Ciscos,
and compares the data with routes in the IRR. The software also
flags prefixes that are reserved by RFC 1597, Address Allocation
for Private Internets.
Available as part of the MRT software distribution at
http://www.merit.edu/~mrt
BGPCheck
BGPCheck obtains and analyzes routing information from BGP4
peering sessions, and compares the data with routes in the IRR. The
software also flags prefixes that are reserved by
RFC 1597, <em>Address Allocation for Private Internets</em>.
Available as part of the MRT software distribution at
http://www.merit.edu/~mrt
PRtraceroute
The 'prtraceroute' tool is a powerful form of traceroute that displays
the Autonomous Systems that a packet traverses. PRtraceroute was developed
by the Pride project.
A version of prtraceroute that queries the RADB is available at
ftp://ftp.ra.net/routing.arbiter/pride/prtraceroute-2.0beta2.shar.gz

PGP-Based Radb Authentication
Follow these steps to take advantage of the new RADB support for
PGP-based digital signatures:
1. Register your public key with the Routing Arbiter Service.
2. Modify your Maintainer object to reflect your use of digital
signatures.
3. Use PGP to sign your RADB transactions.
