Any luck tracking down the reason why some routers inside Sprint kept announcing the routes long after the source was removed during either the incident last Friday or the other incident on Feb 3-4, 1997? >For those of you following the "incident" on Friday, I have now implemented >ip-based filters for MAI.NET and their downstream neighbors.

Internet Traffic Data
by Robert Olshansky 28 Apr '97

28 Apr '97

Hi, K Claffy at LANR suggested I contactb you. At GTE Labs we are working on design of IP backbone facilities for ADSL access services. One of the challenges is to be able to project traffic growth per ADSL useer for the next 3-5 years. Can you direct me to sources of the followinmg: (1) Measured internet traffic statitics at NAPs for the past two years. (Info available at NAP Web sites that I have found is only for the last 5-30 days.) (2) Some measurements of growth of traffic/user over the past two years. So, for a fixed or known user population ( eg a Univ campus or an ISP's modem pool) how has traffic per user grown? (3) Anything else that would be useful. So I would greatly appreciate it if you could direct me to some source.

Wow, AS7007!
by Stephen A Misel 28 Apr '97

28 Apr '97

I happened to be in one of our 7505 routers this afternoon when POP -- all of a sudden most of the internet disappeared! I immediately thought it was me, but looked around and saw this AS7007 broadcasting MY routes! It wasn't for all of our network space -- We have several /18's here, and it seemed only the first /24 of each CIDR was affected. When I found a workstation at the end of the /18, we got the whois info for 7007 -- Florida Internet Exchange, and called them. They claimed to have a customer broadcasting some bad routing information and unplugged their router. A few moments later, the internet stabilized and I started seeing real routes. Correct me if I'm wrong, but: (1) We're going to read about this in EVERY computer magazine, newspaper and TV as "the end of the internet?" (2) Access lists by backbone providers *should* have prevented this. (3) Does or does not the RADB and other routing registries (MCI's, etc) prevent this? I bet this hole will be patched up real soon! Steve

Kent, Savvis only has the GRF1600 in productions, we have ordered a couple of the GRF400 for our test bed. The GRF1600 was the first and only router from NetStar, but NetStar already had planned the GRF400 b4 the Ascend days.....

"Which Internet?"
by Robert E. Seastrom 27 Apr '97

27 Apr '97

Whilst investigating why my routing table size suddenly jumped by 5k routes, I discovered that Advantis (AS 2685 at MAE-E, origin AS 3082) was leaking all sorts of more-specifics for various networks into the bgp mesh. Yeah, I know I should be running bogon filters... Anyway, I called up their NOC to complain, and when I explained the situation I was asked which Internet I was calling about. Then when I asked to be transferred to a supervisor, the "support" person became argumentative and didn't want to transfer me. I had to be rudely direct and demand to be transferred before I was put on hold for five minutes and then informed that the supervisor was out to dinner. Come on Advantis, get it together. ---Rob

MAI.net filters.
by Jason Swain 27 Apr '97

27 Apr '97

For those of you following the "incident" on Friday, I have now implemented ip-based filters for MAI.NET and their downstream neighbors. This will prevent MAI or their downstream neighbors from advertising routes other than their own. As well, Vince from MAI has made considerable effort (along with Jack Dolan from Bay Networks) to add access-lists on their router to ensure if there is a problem, it doesn't propagate outside their network. Keep on keepin' on, Alex Sprintlink

Just to make small correction to my Apology post of yesterday, it was not Net Access Corporation, but Net Access of Philadelphia that offered assistance, aka Avi Freedman. I didn't realize that there was a "Net Access the Lesser". -Vincent

Re: NSI SAYS FCC SHOULD ASSUME INTERNET REGISTRATION FUNCTIONS
by Joseph T. Klein 27 Apr '97

27 Apr '97

Keep the agencies of the United States government out of this. This sounds like NSI is trying to wiggle out of participation in CORE. NSI does not like a solution that provides no guarantee that NSI will be one of the new registries. This is Washington politics - SNAFU and FUD. Operators, read the documentation and decide for yourself. http://www.iahc.org/ The IETF COREdb working group is defining a technical solution to "too much bureaucracy." Who thinks the FCC can be less burocratic than a shared database? Do I see any hands? If you agree with the IAHC solution then show your support and advocate that your company sign the MoU. --- On Mon, 21 Apr 1997 23:50:18 -0700 "Charles R.
