Re: FCC proposes higher speed goals (100/20 Mbps) for USF providers
Is it? I mean, as an industry, we already recognize that the average user downloads approx. 5 times more than they upload. In fact, we use it to bash users who want a synchronous speed... tell them that's unreasonable. I get your point, that if you try to use the outliers corner cases as your "measure", that's a problem. And I agree that game companies might get lazier in terms of efficiency and distribution methods. I'm just saying we need to be careful to have the conversations, and be open to them. We need to provide good, well-thought-out reasons, and justify our reluctance to hit "low profit" areas. Especially when we work in a sector that's being provided billions of dollars a year to do that very thing. Short quips like "Downloading is a really bad thing to use as a reason" overly simplify the (real) problems and needs down to insulting sound bytes when talking to the public. I realize you're talking to an in-group here, and might not have said the same publicly, so I'm not being overly critical, it's just an observation to clarify my own point Sincerely, Casey Russell Network Engineer <http://www.kanren.net> 785-856-9809 2029 Becker Drive, Suite 282 Lawrence, Kansas 66047 XSEDE Campus Champion Certified Software Carpentry Instructor need support?

Re: FCC proposes higher speed goals (100/20 Mbps) for USF providers
To be honest, I don't know, I'm not a money person, I just turn knobs. But apparently it costs more than $130 billion dollars. In the US alone. That's what USAC has distributed to carriers in the US in the last 20 years. Last year was north of 8 billion. That's just USAC and that's just for getting high speed to rural areas, underserved communities, and Community anchor institutions. I don't know if that's too much or not enough, but it seems like a lot to me as a taxpayer when I consider how hard dozens of us had to fight to get ANY carrier to bring fiber to our community anchor institutions 6 or so years ago. But my point was only that if we keep arguing against change and against pushing barriers, then we are what customers (or members) say we are. obstinate, greedy, uncooperative, and unsupportive of their goals. I don't think you're any of those things, I just think we need to stop setting limits FOR customers and be open to a conversation about how to get to (insert wild and crazy, super cool goal here). All the time being as realistic as we can about how to do that.

Re: Juniper configuration recommendations/BCP
Forrest, Between Jason and Justin, (and now others probably) they've captured what I was already typing. Basically, that as soon as you create a loopback interface (with a L3 IP) you need to start planning your firewall filter for it. Most of it is as simple as creating filters for SSH and other administrative access to the loopback address, but some of it is not at all intuitive if you're coming from a Cisco/Brocade world. The loopback filter protects the RE, and, can, in many cases affect traffic flowing across transit interfaces, in a way that in a Cisco shop you would never have never considered. On a Juniper, if it will be processed in just about any way by the routing engine (even just a few packets in the flow) you need to account for that. It's not as daunting as it sounds, but it needs to be accounted for. I'll let their comments fill in the rest, because others have already provided good resources.

Re: Network Speed Testing and Monitoring Platform
I don't think a raspberry pi will reliably fill a full Gig and keep it full (maybe that's not required in this scenario), but I've installed a Linux based OS with the PerfSONAR tools (including iperf) on a couple of different mini PCs in the "few hundred dollars" price range. The last one was the Liva X from ECS. It was more than capable of filling 1G circuits with traffic and keeping them full without loss or wonky results due to things like CPU overrun or other processes causing bus contention. I'm pretty sure the Liva X is retired now, but their current gen should suffice as should a number of comparable competitors.

It's not exactly a measurement of "user to content" but CAIDA has swarms of Raspberry Pi nodes all over the world, that constantly measure... well, a lot of things, but they continually also monitor traceroute paths to each other.

Re: improving signal to noise ratio from centralized network syslogs
+1 for Graylog, you can pour ALL your syslog data into it, and then configure what are called streams. Streams are a way to whittle down the incoming log flows and see something LESS than everything. You can create a stream that only shows these 6 devices, or one that only shows log info from the RPD daemon on your Juniper routers. In your case, you could use the stream rules to create a stream that filters out the background noise with regex expressions. You're not losing anything, you still have the full log data captured, and you can see it in the portal, but if you click on one of your streams, you see filtered data based, on your rulesets. We've been using it for about 2 years now I think. It's open source, easy to set up, supports LDAP, multiple input types (beyond just udp syslog), and the community is pretty solid.

Re: IPv6 oddness in Comcast land...
(I first sent this directly to Valdis instead of the list, so my apologies to Valdis for getting this twice) Greetings, I'm afraid I can't hand the ultimate solution, but I can point you in a direction. Sounds like you probably have an IPv6 neighbor discovery problem. Most likely (since that's where the change occurred) it's between your WRT and the Comcast CPE (I assume a cable modem) or the first active piece of the upstream cable plant. But It'll be the first Comcast device actually speaking Ipv6 to your WRT. I've seen this happen several times in new (or changed) peering links with other providers (where dissimilar equipment, or new ACLs) are involved. Typically what's happening is that an ACL or firewall rule on one device isn't allowing that devices interface to speak fully over the new link, and that's preventing IPv6 neighbor discovery from happening properly between two adjacent devices. (In this case those devices are likely your WRT and the first upstream Comcast device speaking IPv6). Since it's your device that changed, you likely won't have a lot of luck convincing comcast to dig too deep into this issue, especially since their device "worked" before and these providers have few engineers on-staff that really understand v6. It's not that there's no one at comcast who can fix it, it'll just take you a while to find them. So without knowing your equipment, I can only offer a few general tips. Look for troubleshooting commands that will show you the ipv6 neighbor discovery status on your device interfaces. See what the status is before a traceroute (when things are broken) and after a traceroute (when things are fixed). If it appears I'm right, go to that Interface and create ACLs or firewall rules to allow the actual ipv6 addresse(s) on that interface to speak (outward) to their local subnet. Be sure to remember you may need to create a rule for the global (permanent, public) address, and also for the link-local address. Some vendors will put the link-local address in the ND solicitation and others will use the global unicast (if it's already been assigned). The RFC suggests the link-local, but also says that the source and destination addresses in the messages need be only "An address assigned to the interface from which the advertisement is sent." If that does help, remember to tighten those new ACLs as much as you can and still have things work. If it doesn't, you'll likely have to engage comcast about the issue, as it may, or may not be this at all. :-) good luck Sincerely, Casey Russell Network Engineer [image: KanREN] <http://www.kanren.net> [image: phone]785-856-9809 2029 Becker Drive, Suite 282 Lawrence, Kansas 66047 [image: linkedin] <https://www.linkedin.com/company/92399?trk=tyah&trkInfo=clickedVertical%3Acompany%2CclickedEntityId%3A92399%2Cidx%3A1-1-1%2CtarId%3A1440002635645%2Ctas%3AKanREN> [image: twitter] <https://twitter.com/TheKanREN> [image: twitter] <http://www.kanren.net/feed/> need support?

You can't have Cisco either if you really mean that.

Re: bad announcement taxonomy
I think Tony's on the right track here. I vote we call this "Route Laundering", the people who do it "Route Launderers", and the routes themselves "Laundered Routes". I actually had a little trouble spelling the different forms of laundering. So I looked them up.. "I can't believe what a bunch of nerds we are. We're looking up "money laundering" in a dictionary."
