Repair Status Au said today that the five cable systems that have been partially repaired are: Flag North Asia Loop, owned by India's Reliance Communications Ltd.; Reach North Asian Loop, owned by Hong Kong's PCCW Ltd. and Australia's Telstra Corp.; Se-Me-We3, owned by a group including Singapore Telecommunications Ltd. and France Telecom SA; and APCN and APCN2, owned by operators including China Telecom Corp. and Taiwan's Chunghwa Telecom Co. A segment of Asia Netcom Corp.'s EAC cable system will be repaired today, Chan said. Ofta did not receive the repair status on the seventh cable, C2C, owned by C2C Group Ltd, Chan said. http://www.thestandard.com.hk/news_detail.asp?pp_cat=11&art_id=37146&sid=11… Internet alert plan to warn on failures Timothy Chui Tuesday, January 30, 2007 A system designed to warn consumers of future breakdowns in Internet connections is being launched by the Office of the Telecommunications Authority next month.

RE: who was the last legit spammer?

> Define "legit" spammer. Do you mean one who was just advertising a > real product, albeit in an objectionable fashion, as opposed to those > who are trying to spread malware or commit fraud? If you can read foreign languages, you are probably still receiving SPAM for legitimate products. Just last year I got some in Portuguese advertising a sort of "dude ranch" resort. And as far as fraud is concerned, Yahoo.com sells banner advertising to fraudulent organizations in Russia who are advertising so-called green card lottery services. The ads are fraudulent because Russian citizens are not eligible for the green card lottery. If you know about the history of Canter and Siegel on USENET you might find it rather ironic that the same scam is now advertised on Russian-language yahoo.com sites. --Michael Dillon

RE: Route Reflector architecture and how to get small customer blocks in to BGP?
by John van Oppen 29 Jan '07

29 Jan '07

Yep, that is a good strategy... No announcement without the right communities sure makes it much harder to leak. We redistribute lots of static routed stuff into BGP, but only announce globally using network statements with route map applying the right communities. So far, we have never leaked internal routes to customers, peers or transit that we are aware of.

Route Reflector architecture and how to get small customer blocks in to BGP?
by Pete Crocker 28 Jan '07

28 Jan '07

Hey all, I know this will start an argument about relevance, but think of it as one network operator trying to help another operator do good and have a network where the potential for stupid routing leaks is minimized... I've got a friend (really, it's not me!) who works at a regional ISP . The previous network designer didn't seem to have much of a clue, and has tons of customer nets in OSPF. So he's trying to migrate them properly to BGP. I know opinions will vary widely, but that's exactly what we're looking for. What pros/cons haven't we thought of? First, they've got a BGP full mesh of all their routers. They're considering moving towards route reflectors. There's 2 core routers per-POP. And anywhere between 5 and 15 edge/aggregation routers in a POP. The current thought is to move to a route-reflector full mesh between all the dual-core routers in each POP. The other alternative is to deploy just 2 route reflectors for the entire network. Can anyone point me towards real-world info on the pros and cons of each approach? There seems to be little public info on why people do what they do, it's more info on how to do it. Next I'm looking for differing advice on getting small customer- assigned blocks in to BGP. Like /29s that are given to fractional T1 customers. Assume that there are /29s assigned to customers. It would be a beautiful world if these /29s could be easily rolled up in to /24s, then have a static route /24 pointed towards the bitbucket, and advertise the /24 in to BGP. But alas the network is not that neat. / 29s are scattered all over various customer aggregation routers. Sometimes it's just one /29 out of a a /24 block that's on another router. Also, there's /22s to /19s per-pop in nice little aggregatable subnets, so at least that's good. - Should he use a permanent static route to the /29, then use a network statement to bring it in to BGP? - Should he use a permanent static route, and redistribute *very* carefully, so that he can do tagging with communities? - Should he use a static route which would be withdrawn if the link went down? This would mean traffic to a down customer would be dropped quicker, but flaps cause more BGP churn. This would mean he's have hundreds to thousands of /29 routes floating around internally. But the /29s would be portable between edge aggregation routers. - Should he have a /24 routed to the bitbucket, and aggregate /29s where he can, and have some exception /29s floating around randomly? The problem here is what if the customer needs to move to another router, because he wants a bigger pipe and his circuit can't be connected to the existing router? - Should he take the hard line approach and force customers to renumber? If they upgrade their service, and have to move routers, they get assigned a new /29 subnet. In this world of NAT, it should be easy! ;) That way he can have nice contiguous blocks to announce. - Would confederations help? Seems like overkill, but he could aggregate at the POP level instead of the router level. How do the rest of you assign out customer blocks? On a per-router basis, on a per-pop basis? How do you keep the number of routes down to a manageable level? How do you make it easy for installation / provisioning engineers to bring up a customer, but never get near the BGP config (assume they'll login to put a /30 on the link interface)? Any pointers to sites on the net that show how real world ISPs setup their route/policy maps? I'm not talking BGP intro stuff like "make sure you don't announce a default to your upstreams" but examples of what bgp communities are used for, what real world filtering is done beyond basics and bogon filtering, etc. I can't even find a good nanog presentation on this. They're all about the basics. Let the floodgates begin! If you want to tell me this is off-topic, please do us all a favor and email me directly. Or don't read it and simply trash it. Nobody wants to hear why you're the on-topic police and what you say goes. -pete

RE: Westin Seattle Outage?
by John van Oppen 27 Jan '07

27 Jan '07

This was not a building wide problem; apparently it did serve to find the failed UPSes in a few places. The building management does these tests several times a year, and at least to the one colo where we had visibility to the building electrical service, we saw the same outages we always see during such a test. It is also worth noting, that I only saw one of about 60 BGP sessions across the Seattle-IX (which is in the building) reset at the time of the work.

We too had probs. I saw only two outages, one around 8PM PDT and one around 9:45PM PDT. I called during the first one, and the people I talked to were obviously in a state, and I had trouble hearing anyone, as they were in an extremely loud part of the data center or something.
