What is the Routing Registry?

Distributed database collectively known as Internet Routing Registry (IRR) RADB, RIPE, CW, ANS, Canet

Providers register routing policyUsed for planning, debugging and

generating backbone router configshttp://www.radb.net/



Can be used by anyone worldwide debugging configuring engineering routing addressing



contact names, email addresses and telephone numbers for an AS

routing policy for an AS (what other ASes does it connect to, which routes do they exchange)

information about routes (most important is which AS originates the route)

several other types of information


What happens if I don’t use a database?

Routing Horror Stories AS7007

filtering would have prevented this

announcing bogus routes


So, I need to use the database because…..

Filters generated off the IRR protect against inaccurate routing information

Makes troubleshooting and debugging easier

Keep track of policySecurityFilter! Filter! Filter!!


Why Bother with all of this?

View of global routing policy in a single cooperatively maintained database

to improve integrity of Internet’s routing

generate router configs protect against inaccurate routing info

distribution verification of Internet routing


Why Bother using the database (con)

Many providers require that you register your policy peering customer relationship

Route Servers


What is Internet2 going to do?

Merit is setting up a database for I2 community source: I2 register Internet2 routing policy and

informationWill be RPSLUp by end of July


Policy Languages

express policy with aut-num objects, route objects, AS-MACROS

currently RIPE-181moving to RPSL

more policy control


What is RPSL?

Routing Policy Specification Language

Designed to replace current language (RIPE-181)

Enhanced and more generalized


How does the language work?

Object-orientedExpress policy in objects

person mntner role aut-num route

Can make sets of objects


Describing Policy

Use the language to describe your relationship with other Peers routes importing routes exporting specific policies

interfaces, MEDs, communities

Router Configuration

Currently configs by hand - slow and inaccurate

Configuring routers using the IRR lots of tools available!!! RtConfig by ISI

route and Aspath filters.Import and export

Filtering is a good thing...
