Is it permissible to advertise number resources allocated by one RIR to a ISP in a region governed by a different RIR? Practical?
Is it permissible, from a policy perspective, for a multi-homed end user to announce the numbering resource allocation received from one RIR (for discussion purposes, let's say ARIN) to upstream service providers in a different region (for example, in the RIPE region)? Is it feasible from a practical perspective? I've looked through IANA and ARIN policy and can't find anything which covers such a scenario. I have seen some things about transferring number resources from one RIR to another RIR, which is similar, but not exactly the same. Rationale: Suppose you are a large global enterprise, truly globalized in practice, not in mere name, and performance concerns aside, you provide failover for Internet access of enterprise users in one region by failing over to internet access in a different region. Since you probably are using 10/8 addressing within your network and you NAT the private IPv4 addresses to a public IPv4 address before sending the traffic on.., so this works. Given lack of NAT66, and the best practice IPv6 numbering which is purported to use globally routable IPv6 addresses within your enterprise network, the achievable way to accomplish the same use possible today in IPv4 would seem to be to advertise the IPv6 addressing from one RIR to a ISP in a region governed by a different RIR (or LIR).

RE: Locations with no good Internet (was ISP in Johannesburg)
I had good luck getting my dad some form of broadband access in rural Oregon using a 3g router (Cradlepoint), a Wilson Electronics signal amp (model 811211), and an outdoor mount high gain antenna. It's not great, but considering the alternatives (33.6k dialup for $60/mo or satellite broadband for $150-$200/mo) it wasn't a bad deal for my dad when you consider that the dialup ISP + dedicated POTS line cost about as much as the 5GB 3G data plan does. Speed is somewhere between dialup and Uverse or FIOS. I get the sense that it is somewhere in the range of 256 - 512 kbps with high latency (Dad's not one for much in the way of network performance testing). -Original Message- From: Michael Sokolov [mailto:msoko...@ivan.harhan.org] Sent: Friday, February 26, 2010 3:35 PM To: nanog@nanog.org Subject: Locations with no good Internet (was ISP in Johannesburg) Daniel Senie d...@senie.com wrote: Better than western Massachusetts, where there's just no connectivity at = all. Even dialup fails to function over crappy lines. Hmm. Although I've never been to Western MA and hence have no idea what the telecom situation is like over there, I'm certainly aware of quite a few places in first world USA where DSL is still a fantasy, let alone fiber. As a local example, I have a friend in a rural area of Southern California who can't get any kind of high-speed Internet. I've run a prequal on her address and it tells me she is 31 kft from the CO. The CO in question has a Covad DSLAM in it, but at 31 kft those rural residents' options are limited to either IDSL at 144 kbps (not much point in that) or a T1 starting at ~$700/month. The latter figure is typically well out of range for the kind of people who live in such places. That got me thinking: ISDN/IDSL and T1 can be extended infinitely far into the boondocks because those signal formats support repeaters. What I'm wondering is how can we do the same thing with SDSL - and I mean politically rather than technically. The technical part is easy: some COs already have CLECs in them that serve G.shdsl (I've been told that NEN does that) and for G.shdsl repeaters are part of the standard (searching around shows a few vendors making them); in the case of SDSL/2B1Q (Covad and DSL.net) there is no official support for repeaters and hence no major vendors making such, but I can build such a repeater unofficially. The difficulty is with the political part, and that's where I'm seeking the wisdom of this list. How would one go about sticking a mid-span repeater into an ILEC-owned 31 kft rural loop? From what I understand (someone please correct me if I'm wrong!), when a CLEC orders a loop from an ILEC, if it's for a T1 or IDSL, the CLEC actually orders a T1 or ISDN BRI transport from the ILEC rather than a dry pair, and any mid-span repeaters or HDSLx converters or the like become the responsibility of the ILEC rather than the CLEC, right? So how could one extend this model to provide, say, repeatered G.shdsl service to far-outlying rural subscribers? Is there some political process (PUC/FCC/etc) by which an ILEC could be forced to allow a third party to stick a repeater in the middle of their loop? Or would it have to work by way of the ILEC providing a G.shdsl transport service to CLECs, with the ILEC being responsible for the selection, procurement and deployment of repeater hardware? And what if the ILEC is not interested in providing such a service - any PUC/FCC/etc political process via which they could be forced to cooperate? Things get even more complicated in those locations where the CO has a Covad DSLAM in it serving out SDSL/2B1Q, but no other CLEC serving G.shdsl. Even if the ILEC were to provide a G.shdsl transport service with repeaters, it wouldn't help with SDSL/2B1Q. My idea involves building a gadget in the form factor of a standard mid-span repeater that would function as a converter from SDSL/2B1Q to G.shdsl: if the loop calls for one mid-span repeater, stick this gadget in as if it were that repeater; if the loop calls for 2 or more repeaters, use my gadget as the first repeater and then standard G.shdsl repeaters after it. But of course this idea is totally dependent on the ability of a third party to stick these devices in the middle of long rural loops, perhaps in the place of loading coils which are likely present on such loops. Any ideas? MS

Some examples for functionality could be: - QOS - NetFlow - DDoS resistance In general the 6500 and the 12000 are hardware based platforms, with the 12000 being more distributed in nature, using linecard resources for data plane (6500 does it too if you have DFC installed). 7200 is a CPU/software based platform, so the same processor does packet forwarding and control plane processing. The 6500 (depends on specific module selection) is more restricted with QOS and NetFlow functionality as it is designed to do very fast forwarding at a relativly cheaper price. The 12000 has everything implemented in hardware, and depends on the engine types (don't use anything other than Eng 3 or 5) has all the support you may dream of for things like QOS and other features. The 7200 is a software based router, which means that it support any feature you may ever dream of, but the scalability decreases as you turn them on. Another option you should consider seriously should be the ASR1000 router, which is a newer platform and has a new architecture. All its features are based on hardware support, and it could actually prove the best choice for what you need. The ASR1002 comes with 4 integrated 1GE ports, which could be all that you would ever need (but it has quite a few extension slots left).

And exactly how are you determining it is 'unused'? Not announced to the internet? (which means virtually nothing as far as 'use' status of an IP block) For pete sake, the time has come to resolve the issues that prevent widespread adoption of IPv6: - resolve RIR IPv6 allocation hassles for requesting end-user orgs - insist on IPv6-capable hardware/services/engineering staff when getting new hardware/services/staff - work toward retirement of IPv6-incapable hardware/software - train staff - start PoCs for IPv6 services (ip transit, DNS, etc) - start requiring IPv6 capability from ISPs which are slow to move (Vendor A, V, S, etc) Many large organizations use public IP space internally and do not announce it to the Internet. Some SPs use public IP space on private MPLS VPN networks to address links to customers to ensure non-conflicting addresses are used. Some companies run large extranets to connect to customers and partners.

RE: Redundant Array of Inexpensive ISP's?
In answer to a question below about experience with similar products... Cisco IOS has the dynamic routing injection feature as part of recent IOS versions. The feature is now called Performance Routing (PfR) formerly known as OER (Optimized Edge Routing) and as of 12.4(24)T, it can optimize routing protocols other than BGP or static routes (called PIRO Protocol Independent Route Optimization), including IS-IS, OSPF and EIGRP. RIP folks should learn about routing protocols :-D PfR does not do compressions/tokenization of the data, so it has no Caching/compression/WAN Acceleration features, BUT it does do dynamic path re-routing based on your policy or observed metrics like latency, packet loss, jitter etc and can also do it based on observed Netflow data and automatic instatiation of IP SLA active probes to see what happens for a RTP data stream marked with dscp 46 or video stream marked with dscp 34 and so on. As of recent IOS versions (12,4(9)T + I think), it can control both inbound and outbound directions, and can do things like send your traffic to ISP X up to bandwidth Bx and then shift traffic over to ISP Y up to bandwidth By to do dynamic load sharing of traffic to IP transit commit levels Not a bad feature for free. Larger scale deployments should probably use a dedicated controller box making the re-routing decisions, but any WAN egress point to an Internet or private WAN provider is your border device used by the master to get information, setup probes and learn netflow data to make decisions. I've used it for testing purposes on enterprise WAN deployment and it works pretty well. We are planning on deploying on a production DMVPN solution when the MGRE bug below is resolved. My main beef is a bug related to use of PfR on mGRE tunnel interfaces and the memory-hog nature of the feature... It will detect your brown-out issues like increased packet loss for traffic through provider X that cause customers to call you about broken applications and will re-route the traffic so you may never even know there was an issue!! The solution is particularly good for enterprises with only a few WAN or Internet exits from a location and for dynamically load sharing traffic to paid-for commit levels to reduce recurring cost and get the most out of existing connectivity without paying burst charges. We've done testing on use for our internet border routing in the advice mode, where is just says what changes it would maek, without actually making the changes.
