I'm trying to learn about BGP and just ran across RPSL. I've seen www.radb.net and know that lots of people are registering their policies here. Are organizations also using these RPSL policies to compile configuration files for their routers (via RtConfig)? Or do they just maintain their RPSL policies and router configurations separately? A few sites do, but I do not think there are many considering how hard it is to express using RPSL a real complete configuration for a whole network.

Since RtConfig used to be unreliable on modern Linux systems (I do not know if the last release has been improved in this regard) I wrote my own tool which generates as-path and prefix-list filters (and uRPF ACLs) for customers and peers using the IRR data and local configuration files listing the neighbors: http://www.linux.it/~md/rpsltool-1.2.tgz My opinion is that maintaining an aut-num object for the purpose of generating your own configuration is pointless, but maintaining proper route and as-set objects will greatly help your peers to build their filters. (Yes, another of these situations where your actions will only benefit the rest of the Internet and vice versa). -- ciao, Marco
