Routing Policy Specification Language
The Routing Policy Specification Language (RPSL) is a language commonly used by ISPs to describe their routing policies.
The routing policies are stored at various whois databases including RIPE, RADB and APNIC. ISPs (using automated tools) then generate router configuration files that match their business and technical policies.
RFC 2622 describes RPSL, and replaced RIPE-181.
RFC 2650 provides a reference tutorial to using RPSL in the real-world.
RPSL Tools and Programs
- RtConfig - automatically generate router configuration files from RPSL registry entries (This software is part of the IRRToolSet)
- irrPT - A collection of tools which allow ISPs to easily track, manage, and utilize the routing information contained in Internet Routing Registry (IRR) databases, for the purposes of maintaining customer and peer BGP prefix-lists
