Routing Table Jump caused by AS4151
I noticed a jump from some 171k to almost 175k in the last days, and checked CIDR http://www.cidr-report.org/:
Top 20 Net Increased Routes per Originating AS
Prefixes Change ASnum AS Description 3263 0->3263 AS4151 USDA-1 - USDA
so I wonder what's wrong with them. Regards, Fredy

they are leaking just about every /24 in several /16's? :( ATT worldnet is passing them on too, perhaps they can smackdown usda? :)

[...hundreds of similar routes deleted...] This looks more like configuration error than like anything more evil (such as fine-grained traffic engineering). AS4151, could you please stop this?

I send a message to my transits (Qwest and Global Crossing) and AT&T. Here is the message I got back from AT&T. James, We're looking into the situation. We'll get back with you shortly.

Edwards [mailto:jamesh@cybermesa.com] Sent: Thursday, November 10, 2005 1:18 PM To: noc@att.net Subject: AS 4151 has deaggregated adding 5k routes I have noticed AS 4151 (USDA) has deaggregated several /17's into /24's adding approx 5k BGP routes. AS 4151 and 4152 are the USDA, 13979 & 7018 are AT&T. Can anything be done to reaggregate some of these routes ?
