boiled down to "numbering on un-announced space breaks PMTUD"... but it doesn't, not by itself (which he later expanded). It only does so in the presence of filtering.
Which is exactly what one might expect to happen. At least it seems to me that RFC 3704 (BCP 84, http://www.ietf.org/rfc/rfc3704.txt) applies. When your traffic is sourced with dubious addresses, you should expect much of it to disappear. And when this happens, you're hurting your customers and your customers' customers (okay, sometimes it's "just" your peer's customers - still a concern in my opinion). -- Tony Rall
