Hi,
as part of our AS-set stuffing experiments (announced, including links to in-depth information, in [1]), we will be announcing unusually large AS-sets tomorrow, Thursday 16 June.
It would be *very* nice if you could announce this at least a week in advance instead of "tomorrow we are going to abuse the internet for some weird testing". Then folks could add some filtering to discard your announcements.
This is *not* a test to see if routers will fall over: we have successfully tested longer AS-sets in the lab on both Cisco and Juniper, and longer AS-paths and AS-sets have been observed in the wild [2,3].
Unfortunately, especially in the case of Cisco's, there are a lot of varying versions, with each and every one of them their own special little bugs. Also don't forget that there are actually people using other setups than C and J boxes. Not that it would be bad when they would fall over, it would be bad if they would keep on transmitting these paths, like what Cisco's tend to do when not forwarding to other peers that the prefix was actually retracted. PS: Don't forget to notify our asian colleagues. Greets, Jeroen
