Hi Can we use same AS to advertise different networks in different location? We would like to use Seattle as production network and New York as testing eg: Seattle: network 66.49.130.0/24 New York: network 67.55.129.0/24 and ipv6 network. Thank you

Fwd: Service Provider Route Flap Damping Deployment Status Survey
by Shishio Tsuchiya 27 Jun '11

27 Jun '11

Dear NANOG Thanks for a lot of answer and comments to the survey. We will close this survey in 25th May 17:30 of the UTC time. If you could answer the survey,could you open url. https://www.surveymonkey.com/s/rfd-survey We will update our draft,and let you know. Regards, -Shishio -------- Original Message -------- Subject: Service Provider Route Flap Damping Deployment Status Survey Date: Fri, 18 Mar 2011 01:56:35 +0900 From: Shishio Tsuchiya <shtsuchi(a)cisco.com> To: nanog(a)nanog.org CC: shtsuchi(a)cisco.com, kawamucho(a)mesh.ad.jp, randy(a)psg.com, cristel(a)iij.ad.jp Dear NANOG, I'm Shishio,Cisco Systems Japan. I,Seiichi and Randy did presentation about "BGP topic" on JANOG27 which held 20th & 21st January 2011 in Kanazawa. http://www.janog.gr.jp/en/index.php?JANOG27%20Programs#qe7ec71d Randy explained "Route Flap Damping Considered Useable". http://ripe61.ripe.net/presentations/222-101117.ripe-rfd.pdf This report explains how to improve today's harmful RFD. We heard various opinion from bgp operators about RFD. So we took survey about "Service Provider Route Flap Damping Deployment Status" on janog(a)janog.gr.jp. We would like to hear more opinions to analyze current RFD operation,problem and so on. Could you please open the following url and answer the questionaire? https://www.surveymonkey.com/s/rfd-survey The JAPAN result summary is below. ----------------------------------- Q1.Do you use Route Flap Damping ? Yes: 5 No: 13 Q2.If you select No on Q1,why? Do not have the need: 3 Did not know about the feature: 2 No benefits expected: 3 Customers would complain:1 Because I read RIPE-378 :2 Other: 3 Q3.If you select Yes on Q1,what parameter do you use? Default parameters: 3 RIPE-178 : 0 RIPE-210 : 0 RIPE-229 : 0 Other: 3 Q4.Do you know Randy Bush et. al's report ''Route Flap Damping Considered Usable?'' Yes: 12 No: 7 Q5.IOS's max-penalty is currently limited to 20K. Do you need this limitation to be relaxed to over 50K? Yes: 10 No: 9 Q6.If you have any comments, please fill this box. -Our peer seems to have damping enabled, and our prefix gets damped sometimes. -We do not enable damping because we think that customers want a non-damped route. -From the perspective of a downstream ISP, if our upstream told us that an outage occurred because a route was damped, I may call and ask "is it written in the agreement that you will do this?" -We use damping pretty heavily -I had RFD turned on until this morning when I discovered our router has CSCtd26215 issues. I would like to turn on a "useful" RFD. ----------------------------------- other reference: https://tools.ietf.org/html/draft-shishio-grow-isp-rfd-implement-survey-01 https://tools.ietf.org/html/draft-ymbk-rfd-usable-00 Best Regards,

Re: Wacky Weekend: NERC to relax power grid frequency strictures

Hi, Yes, transforming DC is not easy. However, DC works good at long haul transmission because a lot of energy is lost in the revers EMF generated by AC a several hundred volts. Some years ago a high voltage DC line was constructed between Oregon and California to deliver power to California. The line converts to DC at one and and back to AC at the other. Then again POTS phones have always used DC. DC is commonly used in telecom equipment. Well into the time of AC Portland, Oregon provided DC to the theater district for use in carbon arc lamps. It might be noted that the 120v RMS at our wall outlets actuality has a peek value of 169.7 Volts from zero. Or 339.5 volts peek to peek.

> It makes little sense to sync to the grid when the generator is only > used when the grid is down I don't know what large DC do but at our large sites we normally get power cheaper in exchange for a load shed agreement. When we got the call we ran some/all of the load on generator so the grid could flatten peaks. At our tv/radio transmitter sites there were no UPS so a break would disruptive. SOP was to run up the gens, sync then parallel the grid. DC just treat it as a power failure with a short break on non UPS service? brandon

Failure to sync = dirty power and a horribly corrupted sine wave. A bit more than watching an old microwave.
