Level3 using uRPF on their access routers
by Lucas Iglesias 14 Feb '05

14 Feb '05

Hi all, Does anybody know if Level3 is performing Unicast Reverse Path Forwarding on it's interfaces with it's customers? Did anybody have problems with this fact (if so)? We have a multihoming customer, and we found out that packets sent to Level3 sourced with IP blocks winning over other provider (the return path not being prefered over Level3) are being filtered on Level3 network entrance (pretty much uRPF behavior), but they told me and they swear they are not using uRPF. Thanks in advanced, ======================== Eng. Lucas Iglesias, CCNP IP Engineering, Tiba S.A Ph: 5411-48068400 ext 6212 ========================

Yes, this includes the former Digex Web Hosting employees (from a former Digex employee...) It does not include the former Digex Leased Line/Intermedia staff - those that still exist.

I'm not financier, but this price seems rather low considering how large Worldcom is/used to be and that it includes all former UUNET, MCI, MFS, WCOM, etc. BTW - did this include Digex as well? -- William Leibzon Elan Networks william(a)elan.net

RE: The Cidr Report
by John van Oppen 14 Feb '05

Hank and Warren are right on. I have seen several ISPs (one of which has been around a long time) who don't even understand the basics of CIDR routing or why they should aggregate their announcements. This same group are the ones who are not subscribed to this mailing list and don't go to Nanog events, and there are surly a large number of them. I think one thing the CIDR report glosses over, with its ranking system is the sheer number of ASes which announce extra routes. At least that is what strikes me when I start punching my local peer (not customer) ASes into the cidr-report website, virtually all of them have an aggregation problem and by percentage of junk announcements, the small ASes are often far worse than the big guys. That being said, perhaps we need some sort of nanog outreach or BGP support community that larger (or clue full) providers can point their less clue full BGP customers towards. The question then becomes, who would maintain such a group and how do we get the large number of currently non-participating ASes involved?

NANOG is not the place to do it. ARIN, as part of their overhead should do an east coast, west coast and Chicago area tutorial at least once a year. And guess what - most of the training material has already been written by the other RIRs. -Hank >The BGP tutorials I've been doing on Sundays at NANOG all cover >aggregation - at least, I seem to end up talking about aggregation in each >one.

I noticed a large jump in prefixes from 4323 this week as well. -Chris -----Original Message----- From: Philip Smith [mailto:pfs@cisco.com] Sent: Friday, February 11, 2005 4:00 PM To: nanog(a)merit.edu Subject: Re: The Cidr Report Frotzler, Florian said the following on 11/02/2005 21:31: >>Recent Table History >> Date Prefixes CIDR Agg >> 04-02-05 151613 103143 >> 05-02-05 152142 103736 >> 06-02-05 152231 103721 >> 07-02-05 152353 103830 >> 08-02-05 152514 103966 >> 09-02-05 153855 104090 >> 10-02-05 154283 104246 >> 11-02-05 154341 104240 > > ~ +3000 routes in one week? Anyone else frightened by this? Yup. From my own Routing Report (due out in a couple of hours), a quick glance shows that the vast majority of the increase comes from ASNs assigned by ARIN (the ASNs from the other three registry regions show minimal increase in announcements). Most seem to come from AS4323. Today they are announcing 2606 prefixes, a week ago they were announcing 844 prefixes. philip --
