Hi Alex, You can usually deconfigure the extra IP's on the box and send them down the tunnel. At worst you do a little proxy arp to tell the router that your vps still serves those addresses. You'll find providers are reluctant to assign /28's and /29's to low-dollar VPS services.

Re: OT: VPS with Routed IP space
Thanks to those who mailed off-list for the BGP thread-jack. Seems like those providers that do BGP would probably route their own space to VPS as well.. (Like OP want. if I understand correctly). Some of them even state that they even SWIP the addresses, which is positive.

Re: High throughput bgp links using gentoo + stipped kernel
I had two Dell R3xx 1U servers with Quad Gige Cards in them and a few small BGP connections for a few year. They were running CentOS 5 + Quagga with a bunch of stuff turned off. Worked extremely well. We also had really small traffic back then. Server hardware has become amazingly fast under-the-covers these days. It certainly still can't match an ASIC designed solution from Cisco etc, but it should be able to push several GB of traffic. In HPC storage applications, for example, we have multiple servers with Quad 40Gig and IB pushing ~40GB of traffic of fairly large blocks. It's not network, but it does demonstrate pushing data into daemon applications and back down to the kernel at high rates. Certainly a kernel routing table with no iptables and a small Quagga daemon in the background can push similar. In other words, get new hardware and design it flow.

Re: Muni network ownership and the Fourth
Not to sidestep the conversation here .. but, Leo, I love your concept of the muni network, MMR, etc. What city currently implements this?

Re: Muni fiber: L1 or L2?
One thing that is bothersome about carriers is that sometimes if they have Tons of fiber to your building, they still will only offer Layer2/3 services. If there's fiber there, I'd like to be able to lease it in some fashion (even if expensive, but preferably not). If a muni is making something that is good for the public, I think they can and should offer Layer2 services, but also make the option to directly get the fibers at a reasonable price .. even for Individuals and small companies. I think services that are offered should also provide the ability to order the subcomponents including Layer1. That should encourage competition, usability, and fun. I'd totally get a 10G from my work to home or whatever.

I want to be 100% clear about what I advocate here: - Muni-owned MMR space, fiber only, no active equipment allowed. A big cross connect room, where the muni-fiber ends and providers are all allowed to colocate their fiber term on non-discriminatory terms. - 4-6 strands per home, home run back to the muni-owned MMR space. No splitters, WDM, etc, home run glass. Terminating on an optical handoff inside the home. Hmmm. I tend to be a Layer-2-available guy, cause I think it lets smaller players play. Does your position (likely more deeply thought out than mine) permit Layer 2 with Muni ONT and Ethernet handoff, as long as clients are *also* permitted to get a Layer 1 patch to a provider in the fashion you suggest? (I concur with your 3-pair delivery, which makes this more practical on an M-A-C basis, even if it might require some users to have multiple ONTs...) Cheers, -- jra -- Jay R.

Re: IPv6 Netowrk Device Numbering BP
Though 2001:abcd::192:168:10:10 was written in a format with both : and . , I think would could take the concept mentioned above and extend it either by making it 2001:abcd::C0:A8:0A:0A or 2001:abcd::C0A8:0A0A Doing the latter wastes less space and let's the host use the upper 32bits of the host portion for vhosts. Ex: 2001:abcd::1:C0A8:0A0A Should be easy enough as something like pxelinux already squishes your v4 address down to do file searching on tftp servers. Ex: /mybootdir/pxelinux.cfg/C25B for 192.0.2.91 I personally have for this use the last 32bits of the v6 address for the v4 dual stack address trick and was happy with it. Still fits with the concept of give each host a /64 On Thu, Nov 1, 2012 at 8:20 AM, Masataka Ohta mo...@necom830.hpcl.titech.ac.jp wrote: Eugeniu Patrascu wrote: You can say it's a IPv4 thinking model, but it's easier to remember that if the fileserver it's at 192.168.10.10 then it's IPv6 counterpart address would be 2001:abcd::192:168:10:10 (each subnet being a /64) That is a clever idea except that it can not always follow modified EUI-64 format aof rfc4291. We should better introduce partially decimal format for IPv6 addresses or, better, avoid IPv6 entirely. Masataka Ohta Another option would be to do both. Assign a fixed address and also let it chose EUI-64. However, I see that leading to confusion. Not sure what good it would do. Is there anything like a standard, best practice for this (yet)? What are other people doing and their reasons? Anyone have operational experience with what works and what does not (and the what does not is probably really of more interest)? Letting the host choose it's own IP can be very tricky and has operational hurdles along the way as it's not that easy to copy configurations across devices during upgrades and maintenance swap outs. -- Zach Giles zgi...@gmail.com
