Big Temporary Networks
by Jay Ashworth 24 Sep '12

24 Sep '12

My best friend just got back from Chicon 7 last week, this year's World Science Fiction Convention. He tells me that the networking at the con hotel, the Chicago Hyatt, was miserable, whether wired or wireless... and that Sprint 4G wasn't much better. I'm talking to the people who will probably be, in 2015, running the first Worldcon I can practically drive to, in Orlando, at -- I think -- the Disney World Resort. I've told them how critical the issue is for this market; they, predictably, replied "We look forward to your patch". :-} I know without a doubt that this is a problem NANOG PCs deal with 3 times a year; is there any collected wisdom on the web already about how this has been dealt with, that I can pore over? Pointers to good archive threads? If not, do any of the people who've already done have 5 minutes to chime in on what they did and what they learned? Cheers, -- jra -- Jay R.

Cisco 7206 IOS for PPPoE Termination
by Shahab Vahabzadeh 24 Sep '12

24 Sep '12

Hello everybody, I am using C7206 VXR NPE-G2 routers as BRAS in my network and the current IOS is *c7200p-adventerprisek9-mz.124-24.T.bin* on them. Also their memory upgraded to 2GB instead of 1GB. And I have near 6500 online user on each of my BRAS and there is no speciefic feature except aaa with radius and ordinary features. There router is also terminating dot1q too because my PSTN centers traffic comes through dot1q vlans to BRAS es. I think I have some problem with current IOS, My CPU Usage is abnormal and Its near %70 or %80. And when I have a network problem and some of PSTN centers goes down CPU go to %99 and it gets problem to recovery. Do you know any good IOS for me as a service provider to use? I heard that some service providers have near 8000 online user on 7206. Thanks -- Regards, Shahab Vahabzadeh, Network Engineer and System Administrator Cell Phone: +1 (415) 871 0742 PGP Key Fingerprint = 8E34 B335 D702 0CA7 5A81 C2EE 76A2 46C2 5367 BF90

TWTC BGP IPv6 /40 prefix
by Ben Bartsch 21 Sep '12

21 Sep '12

I am trying to add a /40 prefix to be accepted by a couple of TWTC circuits we have in Louisiana (Shreveport and Baton Rouge). My only options available are /32, /48, /56, /64 in the web portal. Is there somebody from TWTC that could contact me off list? Thanks. -bb

Re: IPv6 Burgers (was: IPv6 Ignorance)
by Richard Brown 20 Sep '12

Another measure of the size of the IPv6 address space... Back on World IPv6 Day in June 2011, Dartware had a barbecue. (Why? Because the burgers had 128 (bacon) bits and we served IP(A) to drink :-) You can see some photos at: http://www.networkworld.com/community/blog/scenes-ipv6-day-barbecue But we came up with another interesting measure for the vastness of the IPv6 address space: If an IPv4 hamburger patty has 2^32 (4.2 billion) unique addresses in its 1/4 inch thickness, how thick would an IPv6 hamburger be (with 2^128 unique addresses)? The answer is... 53 billion light-years. It's straightforward unit conversions. There are 2^96 IPv4 Hamburgers at a quarter-inch apiece. That's 2^96 inches/4 (2^94 inches). Switching to decimal units, 1.98x10^32 inches; 1.65x10^27 feet; 3.13x10^23 miles; and then continuing to convert to light-years. A good tool for this kind of wacky unit conversion is Frink (http://futureboy.us/fsp/frink.fsp?fromVal=2%5E94+inches&toVal=lightyears) which can do this in one shot. Simply enter: From: 2^94 inches To: lightyears and you'll see the answer!

I've had it pointed out to me that I talked to those folks on the list, during NANOG 53 or its runup. Um, "oops". Sorry. :-) I still don't think we can afford you, though. Cheers, -- jra -- Jay R.

Yes, and I'm told by my best friend who did attend (I didn't make it this year) that the hotel wired/wifi was essentially unusable, every time he tried.
