IRR import: and export: parameters are poorly implemented. Is anyone actually validating more than the origin with IRR?I think "validating" is the wrong verb for IRR. "Provisioning" may be more accurate. As an example, my AS293 peers with AS6509. In the AS-SET that they publish, AS6509:AS-CANARIE, the "members:" field for instance lists AS271:AS-BCNET-MEMBERS which then lists AS271 in it's members. An inverse query to an IRR whois server from such a tool as 'bgpq4' walks this tree to generate a list of prefixes applicable to in effect, a given path presuming you know what IRR object to start with. That is where import/export typically comes into play.
I get the data structure, but are there are any tools that implement the above and allow paths to be validated? ...
