a switch to be used that stops processing this sort of thing, in an internet core (and honestly most enterprise core) routers, all I want is packet-in/packet-out. there's no need for anything else, stop trying to send line-rate packets to the cpu. > Punting transit is not only not stupid but also necessary in hardware routers > which cannot handle every case in hardware (which is all routers). no. all you need is a default 'do not process these, just fwd them' switch. (or, a switch at any rate that the operator can select one way or the other, they SHOULD know what is the best for their deployment). > There should just be adequate way to limit these and there should exist > default > limitation. I really think zero limit is the right limit... (for a large number of deployments)
