Steve,
That's simply propagating FUD, and I think that by
making such sweeping assumptions, you are doing the
Internet community a disservice.
Is RFC2267-style filtering a perfect solution for
every situation? No. Sure there are some scenarios
where it foo bars transit traffic, but in the larger
scheme of things, most dual-homed networks are not
providing transit.
Does it impact router performance? Perhaps. It really
depends on various arbitrary issues.
From an architectural perspective, it is very important
_where_ you filter to be effective, not cause transit
problems, and not make smoke roll out of the back of
the equipment.
Will it stop bogon source packets from being injected into
the Internet, so that anyone foolish enough top launch a
denial of service attack can be traced back, identified, and
prosecuted? Absolutely.
