I'm back...
by Charles N Wyble 12 Aug '11

12 Aug '11

Hey folks, Been months since I've graced the NANOG list. Been a busy year so far. I see the same exact v6 threads going on as when I left. LOL. Like a forest fire that won't die. :) Go Owen and your band of merry men! And OSPF vs ISIS. Glad to see nothing has changed. I have a few threads queued up 1) My experiences with ipv6 on the content provider side using a FLOSS stack 2) An experiment: Redundant array of inexpensive hosting providers (or do you/when do you really need bgp/expensive data centers?) 3) Current state of FLOSS data center suite 4) NANOG Home Networks - What's in your closet? Hopefully this stuff is on topic for NANOG. Charles (shaking things up) :)

Experience with Juniper MX-80s
by Babak Pasdar 12 Aug '11

12 Aug '11

Hello NANOG Group, I am curious if anyone has any experiences positive or negative with Juniper MX-80s. Our recent experience with Juniper has not been great both in terms of new product offerings (SRX) and software bugs in the recent revs of Junos for the MX platform. I want to know if the MX-80 functions as advertised and in specific can properly handle two full IPv4 and IPv6 BGP feeds Thanks in advance, Babak -- Babak Pasdar President & CEO | Certified Ethical Hacker Bat Blue Corporation | Integrity .

Re: IPv6 end user addressing

Owen, The fact that you're immediately going to routing means you don't understand the problem. The costs I'm talking about don't have anything to do with routing or any of the core gear and everything to do with the pieces at the customer premise. Routers cost more to purchase than bridges because there is more complexity (silicon & software). Routers also cost more to manage for a service provider in almost all cases for residential customers. There are reasons to deploy routing CPE in some cases (the use cases are increasing with IP video in DOCSIS systems) but they are still very nascent.

I worry when people start throwing around terms like routing in the home that they don't understand the complexities of balancing the massive CPE installed base, technical features, end user support, ease of installation& managemenet, and (perhaps most importantly) the economics of mass adoption. This one of the choices that made DSL deployments more complex and expensive than DOCSIS cable deployments which in turn caused the CEO of AT&T to say their entire DSL network is obsolete. >> http://goo.gl/exwqu >> >> >> >> On 8/10/2011 12:57 PM, Tim Chown wrote: >>> On 10 Aug 2011, at 16:11, Scott Helms wrote: >>> >>>> Neither of these are true, though in the future we _might_ have deployable technology that allows for automated routing setup (though I very seriously doubt it) in the home.

This same Vendor C wants us to upgrade our 7206VXR's to ASR1K's just so we have the (hopefully working) IPv6 features in IOS-XE that are broken in 12.x.

The IPv6 Broadband featureset on the ASR platform starting from IOS-XR 3.1 is a vast improvement on its predecessors. Biggest hassle with IPv6 in production right now: DNS support is woefully undercooked. I don't think anyone has put anywhere near as much effort into making it fluid, user-friendly, and automated. Simple questions like, "How are reverse mappings supposed to work when you can't predict an end-user's address?" have no good answer. If any systems folks want a nice meaty problem domain to focus their efforts on, DNS would be da shiznit. - mark -- Mark Newton Email: newton(a)internode.com.au (W) Network Engineer Email: newton(a)atdot.dotat.org (H) Internode Pty Ltd Desk: +61-8-82282999 "Network Man" - Anagram of "Mark Newton" Mobile: +61-416-202-223
