One thing that I have on my todo list is to look at the aggregation potential in each registry region. I guess it could take Tony's CIDR report and split it on a per region basis?
It's listed on a per AS basis at http://www.mcvax.org/~jhma/routing/all.html. James, when will the IOS config maker become available? :) (he claims as soon as he has power to his laptop..:) )
The biggest problems are from surprising places. Private AS leakage comes mostly from the US, deaggregation comes from every region,... It's usually, but not always limited to newer providers...
So you mean we need a "aggregation for Newbies"? What might be useful was if RIPE (for an example) at the LIR courses explained the problem.
However, fact is that it's up to us as a community to let the operators announcing huge amounts of unaggregated or bogus routes that this is wrong and causing a problem. Just as you contact ISP:S abuse contacts or NOC:s for other problems. If enough people show them that we care I am sure they will act (or if you CC their upstream their upstream might care).
I don't think anyone really cares any more. There is enough memory and CPU in the big routers these days, it seems... I could be wrong about both assertions.
Well disk space is even cheaper but people still care about SPAM. But I might be wrong too.
All this will become a real issue once the number of prefixes being announced becomes a problem for BGP convergence, or storage space on the routers runs out...
Well, what strikes me is that aggregation keeps popping up at NANOG, RIPE, IETF etc and everyone (more or less) agrees we needs to fix this. Still... I agree we need a bigger carrot (and there is no bigger carrot than money) to achieve this. The question is just how and what? But it's not the registries' job. Maybe we could define Tier-0 ISP:s as upstreams with a aggregation conscious? I doubt that more mailinglists and reports will help. And more meetings with concensus will not add much. Having things automated (a script mailing the corresponding AS) might be one idea, but I agree that more mails will not do it alone. - kurtis - Kurt Erik Lindqvist Kurtis.Lindqvist@KPNQwest.SE KPNQwest Sweden @ The speed of light http://www.kpnqwest.se PO Box 23163 S-10435 Stockholm
