Re: [nznog] AKL-IX and domestic vs. international

I believe (from memory) that while the APE route servers insert 9560 into the as path of routes they are distributing, AKL-IX and Megaport do not insert theirs into the path, so you may find that traffic errs toward the new IX players anyway all things being the same given the shorter ASpath.

I think the most pragmatic solution on your end is to have local preference the same for akl-ix and ape and use bgp weight so that for the same as-length it'll prefer akl-ix. the hops with vocus in them should have an extra asn in the path, and if it was just a prepend it'd be even between ape and vocus/akl-ix.

i think it's semi-reasonable that things behave like they do. "it's just the way it is".

Just interested in people's thoughts on this situation) We, Inspire/AS17705, recently peered at AKL-IX. I was interested in using this peering exchange as much as possible so we have tended to prefer AKL-IX routes over any other peering exchange (though we still prefer bi-lats, private interconnects, etc, over AKL-IX). Simple stuff.. We learnt a lot of routes off AKL-IX. We started sending traffic out via. AKL-IX. Cue customer complaints. In general, we were sending all traffic to AS4826/Vocus out via AKL-IX. I believe if another ISP had Vocus as an international provider the traffic would ingress that ISP via their international pipe. This led to one customer having packet loss over a VPN (I'd assume the far end had congested international) and another customer getting billed for this traffic as international. We ceased learning Vocus routes from the AKL-IX. Problem solved... Except, this doesn't really sound ideal to me. If Vocus are announcing routes to AKL-IX (their choice) I would like to be free to use them. What should we be doing in a situation like this? What should Vocus be doing? Am I just making a mountain out of a molehill here and should I just shut-up and leave my current fix in place? Cheers Dave
