2 Internet Routing Registries2 What is the Routing Registry? zDistributed database collectively known as Internet Routing Registry (IRR) yRADB, RIPE, CW, ANS, Canet zProviders register routing policy zUsed for planning, debugging and generating backbone router configs z

3 Routing Registries3 What is the Routing Registry? zCan be used by anyone worldwide ydebugging yconfiguring yengineering routing yaddressing

4 Routing Registries4 What is the Routing Registry? ycontact names, addresses and telephone numbers for an AS yrouting policy for an AS (what other ASes does it connect to, which routes do they exchange) yinformation about routes (most important is which AS originates the route) yseveral other types of information

5 Routing Registries5 What happens if I dont use a database? zRouting Horror Stories yAS7007 xfiltering would have prevented this yannouncing bogus routes

6 Routing Registries6 So, I need to use the database because….. zFilters generated off the IRR protect against inaccurate routing information zMakes troubleshooting and debugging easier zKeep track of policy zSecurity zFilter! Filter! Filter!!

7 Routing Registries7 Why Bother with all of this? zView of global routing policy in a single cooperatively maintained database zto improve integrity of Internets routing zgenerate router configs yprotect against inaccurate routing info distribution yverification of Internet routing

8 Routing Registries8 Why Bother using the database (con) zMany providers require that you register your policy ypeering ycustomer relationship zRoute Servers

9 Routing Registries9 What is Internet2 going to do? zMerit is setting up a database for I2 community ysource: I2 yregister Internet2 routing policy and information zWill be RPSL zUp by end of July

10 Routing Registries10 Policy Languages zexpress policy with aut-num objects, route objects, AS-MACROS zcurrently RIPE-181 zmoving to RPSL ymore policy control

11 Routing Registries11 What is RPSL? zRouting Policy Specification Language zDesigned to replace current language (RIPE-181) zEnhanced and more generalized

12 Routing Registries12 How does the language work? zObject-oriented zExpress policy in objects yperson ymntner yrole yaut-num yroute zCan make sets of objects

13 Routing Registries13 Describing Policy zUse the language to describe your relationship with other Peers yroutes importing yroutes exporting yspecific policies xinterfaces, MEDs, communities

14 Routing Registries14 Querying the Database zwhois -h AS237 zwhois -h MAINT-AS237 zwhois -h

15 Routing Registries15 How to Register your IRR policy zRegister one or more maintainers zRegister AS and policy information zRegister Routes zDescribes your import and export policy yAt the very least, provides contact information
