RE: Route Reflector architecture and how to get small customer blocks in to BGP?

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.

I think of it as a network-level instance of "that which is not expressly permitted is denied" which everyone applies for services on their hosts, right :-) Cheers, Joe -- RSUC / GweepNet / Spunk / FnB / Usenix / SAGE

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. From what I could understand through the noise of some really loud fans or a generator, there was a power test of some kind, and a generator flaked or something.

Electric utilities, IP addressing, and BPL (was Re: Google wants to be your Internet)

It's rare I've seen a thread on NANOG that's so pertinent to my own situation. I work for a fairly large utility faced with these very problems. We are developing a ~half $billion project to replace our electric meters with 2-way communicating ones, and have several other things going, such as "intelligent grid" projects that will grow the size of our networks many times over. I've also been on a broadband over power line (BPL) project for a year and a half, and have a good understanding of how & where it works, and where it doesn't. The US electric distribution grid, is, for the most part, quite dumb. There are various SCADA and fault protection systems out there, but not everything is automated, and certainly not everything is covered. For example, when the power goes out somewhere, almost all of the time, we don't know until we receive calls from customers. Not a proactive system. Not the level of service that our customers want. Intelligent communicating meters are at the core of the modernization of the grid (and of utility profits, if you look at it in certain ways). You'll eventually find these meters tied to time-of-use electric rates (more $$$ during peak times), as well as used as part of an overall instrumentation effort of the grid. Demand response is also a piece of that puzzle. Shaving a few megawatts on a hot day by reducing load (think 50,000 thermostats having their temperature settings moved up a few degrees on a really hot day) can mean avoiding building power plant and/or transmission line capacity. The electric meter is potentially the utility's gateway into a neighborhood or home network, and could enable those applications. Instrumentation of the grid will also take sensor nets, on the order of tens or hundreds of thousands of endpoints per distribution system. We'll find similar networks in customer homes - the load control boxes, the thermostats, etc., that will extend from our edge. Potentially, hundreds of thousands more networks there. There are some utilities that will use BPL as a partial or whole transport for metering & other utility applications, with the notion that there's enough bandwidth to handle residential access services as well (this will often be via a tenant or other 3rd party). While BPL business cases won't be made without utility applications like meter reading, it's unlikely they'll be made without an access play. The other stuff just doesn't require the bandwidth. Do we need IP all the way to the edge of the network? We don't think so. But the alternatives, such as adding ZigBee mesh networks beyond the IP edge, have their own problems of scale & complexity. I've been following the notion that however far our IP network extends out, IPV4 and RFC1918 have plenty of space for us. I'm reminded by this thread, however, that M&A activities, among others, might one day bite us for making that assumption. -jg
