Meet Mr. RPSL – An Meet Mr. RPSL – An IntroductionIntroduction

RPSL allows a network operator to be able to RPSL allows a network operator to be able to specify routing policies at various levels in the specify routing policies at various levels in the Internet hierarchy; for example at the Internet hierarchy; for example at the Autonomous System (AS) levelAutonomous System (AS) level

At the same time, policies can be specified At the same time, policies can be specified with sufficient detail in RPSL so that low level with sufficient detail in RPSL so that low level router configurations can be generated from router configurations can be generated from them.them.

RPSL is extensible; new routing protocols and RPSL is extensible; new routing protocols and new protocol features can be introduced at new protocol features can be introduced at any timeany time


Object oriented languageObject oriented language RPSL is based on RIPE-181, a language used to RPSL is based on RIPE-181, a language used to

register routing policies and configurations in register routing policies and configurations in the IRRthe IRR

Operational use of RIPE-181 has shown that it Operational use of RIPE-181 has shown that it is sometimes difficult (or impossible) to is sometimes difficult (or impossible) to express a routing policy which is used in express a routing policy which is used in practice practice

RPSL has been developed to address these RPSL has been developed to address these shortcomings and to provide a language which shortcomings and to provide a language which can be further extended as the need arises can be further extended as the need arises

RPSL obsoletes RIPE-181RPSL obsoletes RIPE-181


RPSL was designed so that a view of the global routing RPSL was designed so that a view of the global routing policy can be contained in a single cooperatively policy can be contained in a single cooperatively maintained distributed database to improve the integrity of maintained distributed database to improve the integrity of Internet's routingInternet's routing

RPSL is not designed to be a router configuration languageRPSL is not designed to be a router configuration language RPSL is designed so that router configurations can be RPSL is designed so that router configurations can be

generated from the description of the policy for one generated from the description of the policy for one autonomous system (aut-num class) combined with the autonomous system (aut-num class) combined with the description of a router (inet-rtr class), mainly providing description of a router (inet-rtr class), mainly providing router ID, autonomous system number of the router, router ID, autonomous system number of the router, interfaces and peers of the router, and combined with a interfaces and peers of the router, and combined with a global database mappings from AS sets to ASes (as-set global database mappings from AS sets to ASes (as-set class), and from origin ASes and route sets to route prefixes class), and from origin ASes and route sets to route prefixes (route and route-set classes)(route and route-set classes)

The accurate population of the RPSL database can help The accurate population of the RPSL database can help contribute toward such goals as router configurations that contribute toward such goals as router configurations that protect against accidental (or malicious) distribution of protect against accidental (or malicious) distribution of inaccurate routing information, verification of Internet's inaccurate routing information, verification of Internet's routing, and aggregation boundaries beyond a single ASrouting, and aggregation boundaries beyond a single AS

RPSL: Getting to know itRPSL: Getting to know it

RPSL constructs are expressed in one or RPSL constructs are expressed in one or more database "objects" which are more database "objects" which are registered in one of the registriesregistered in one of the registries

Each database object contains some Each database object contains some routing policy information and some routing policy information and some necessary administrative datanecessary administrative data
