ISP Filter Policies
by Adam Clark 23 Aug '07

23 Aug '07

I've noticed that http://www.nanog.org/filter.html is a little out of date, and I was wondering if anyone knows whether any ISPs currnetly have issues with /24 BGP advertisements for blocks outside of the traditional Class C space? We have some migrations to do from one space to another and having the ability to do some /24 advertisements during that period would be greatly helpful. I see that even Verio now accepts prefix lengths /24 or shorter. Thanks, -- Adam Clark Senior Network Engineer Canada Web Hosting

more on Cleveland fiber cut

http://www.cleveland.com/news/plaindealer/index.ssf?/base/business-3/118786… Vandals cut Internet line in Cleveland, causing online delays Thieves seeking copper suspected in online glitch Thursday, August 23, 2007 Shaheen Samavati Plain Dealer Reporter Notice your Internet connection acting up earlier this week? You weren't alone. Cleveland vandals - possibly copper thieves - probably caused delays for millions of Internet users around the world on Sunday night and much of Monday. Near Euclid Avenue and East 65th Street, someone apparently used a chain saw Sunday afternoon to cut through a high-capacity Internet trunk line, part of the backbone of the Internet. Although the thieves may have been seeking copper, there is no copper in fiber-optic cable. When workers went to fix the underground cables, they found that the coil of replacement cable they brought from a warehouse had been damaged by a gunshot, making it unusable. The setback meant things weren't brought back up to speed until Monday afternoon. The damaged trunk line is owned by Adesta LLC of Nebraska but is leased by several Internet wholesalers, including Cogent Communications, Level 3 and TeliaSonera. ..... [I've lost track; who is Adesta? Or rather... WHo did they buy out who'd installed the fiber?] -- A host is a host from coast to coast.................wb8foz(a)nrk.com & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433

Re: Cogent latency / congestion [NEW INFO]

For those of you interested in a "from the ground" report, read here : http://blog.cleveland.com/business/2007/08/vandals_try_to_download_copper.h… Somebody used a chainsaw on a cable at Euclid & 65th (a mostly abandoned industrial area). http://maps.google.com/maps?f=q&hl=en&sll=37.0625,-95.677068&sspn=43.799322… The roll of replacement cable was subsequently found to be damaged by gunfire (it'd only take one shot to a spool to ruin the entire lot). No indication that this happened in conjunction with the first incident. The local cops are calling it a case of "dumb criminal", specifically that someone thought there was copper in the line (yes, they rip it right off poles here -- and sometimes, even try to climb the fence at a substation -- with interesting results) : http://www.newsnet5.com/news/13946673/detail.html Cheers, Michael Holstein CISSP GCIA Cleveland State University

Hi, In my case, I have 6453 and 174 for transit. I want to get to 577 which is directly connected to 6453 and 174. 577 has a higher local pref on paths via 174. Short of shutting my 174 session (or some deaggregation), I dont have a way to influence how 577 gets back to me. I can easily exit out 6453, but it does nothing for the return packets. I have enough capacity on 6453 to handle all my traffic, but its a Draconian step to take and some traffic via 174 is fine and would be worse if I fully shut the session. (ie. peers of 174 in Toronto) ---Mike

So I dont think they would let me influence their exit path to make them pay Teleglobe more money :) But yes, community tickery can be quite helpful, but it wont always do the trick. ---Mike

CIsco Ons Questions
by Andrew Matthews 22 Aug '07

I have a few questions regarding a Cisco ONS. 1. Are there Channelized OC cards for the ONS? or are they just raw ports that can be done anyway needed? And if so are there OC3 and OC12 Channelized? 2. If 1 is true, can the ONS mux circuits? For example; Can i take 2 OC3s on one side, and mux them into one large OC12? 3. If all are true, what oc3 and what oc12 card is needed? and i think its the IR since i'm not going over 70km between the ons and the connecting device. Thanks Andrew
