IRRToolSet is a suite of policy analysis tools to operate with routing policies in RPSL [RFC 2622] format, registered in an Internet Routing Registry(IRR). The main goal of the project is to make routing information more convenient and useful for network engineers, by providing tools for automated router configuration, routing policies analysis, and maintenance. This package contains the programs rtconfig, peval and rpslcheck. IRRToolSet started life as RAToolSet from ISI.edu, was then kept by RIPE NCC for a while, and is currently maintained at ISC. THIS IS A DEVELOPMENT VERSION (although a release candidate).
