At this time I am receiving a ton of bogus routes originating from AS701. This AS has hijacked all the /24 subnets of 128.1 through 128.1xx. Since the more specific route prevails in the cidr world they have managed to wipe out my network 128.9.0.0 not to mention a hundred other 128.x networks.
Isn't this the kind of problems that the Doran filters are supposed to prevent?
I understand that it is not to everyone's benefit to filter on the /19 boundary like Sprint does but it seems to be prudent to adopt a /8 filter on most of the old class A space and a /16 filter on the old class B space. Other than the need to update these filters as the former class A space is subdivided I can see no major downside.
And networks that 1) do prefix filtering of peers, or 2) have the satanic phylters in place didn't even notice yesterday's snafu. -dorian
