the horse is dead and partially dismembered, but we're still whacking away.
Hopefully this will target the blows at the parts that are still not jelly.
1) Filtering is a good idea. If everyone did it, it would be a great idea.
Getting everyone in the Internet to do anything is impossible, so maybe it's
not the most useful solution.
2) there are groups working on ways to do announcement AS verification. there
are two efforts in the IETF right now, in the RPS and IDR working groups.
These will allow people to do distant source verification. These solutions
look far more promising to me that saying everyone should filter. There is
work beyond either of these proposals that gets harder, but both of these look
to do a big chunk of problem for accidents like this.
Harping just a little more, unless the IP registries take the lead and push
their hierarchical allocation tree data out and ISPs pick it up and do useful
filtering with it, this problem will continue to occur regularly. Talk to your
registry and your router vendors to start getting the pieces in place to get a
I think it is safe to say that more mail on NANOG saying people should
neighbor filter will not solve this problem. Lets work on things that will.
