Re: In case anyone hadn't seen this

[Enke Chen <enkechen () cisco com>]

The solution to this problem is filtering, which has been known for 
a long time. 

The provoders that have been filtering on the customer edge seem to 
have done much better in terms of providing sanitized routes. I am
wondering how many such major outages need to occur in order to 
convince some providers to do customer filtering?
