using "reserved" IPv6 space
by -Hammer- 20 Jul '12

20 Jul '12

OK. I'm pretty sure I'm gonna get some flak for this but I'll share this question and it's background anyway. Please be gentle. In the past, with IPv4, we have used reserved or "non-routable" space Internally in production for segments that won't be seen anywhere else. Examples? A sync VLAN for some FWs to share state. An IBGP link between routers that will never be seen or advertised. In those cases, we have often used 192.0.2.0/24. It's reserved and never used and even if it did get used one day we aren't "routing" it internally. It's just on segments where we need some L3 that will never be seen. On to IPv6 I was considering taking the same approach. Maybe using 0100::/8 or 1000::/4 or A000::/3 as a space for this. Other than the usual "Hey, you shouldn't do that" can anyone give me some IPv6 specific reasons that I may not be forecasting that would make it worse doing this than in an IPv4 scenario. I know, not apples to apples but for this question they are close enough. Unless there is something IPv6 specific that is influencing this.... -- -Hammer- "I was a normal American nerd" -Jack Herer

Why use PeeringDB?
by Chris Grundemann 18 Jul '12

18 Jul '12

Peering Experts, I am currently working on a BCOP for IPv6 Peering and Transit and would very much appreciate some expert information on why using PeeringDB is a best practice (or why its not). All opinions are welcome, but be aware that I plan on using the responses to enhance the document, which will be made publicly available as one of several (and hopefully many more) BCOPs published at http://www.ipbcop.org/. Also, if there are those among you who would like to review the entire document and perhaps volunteer as a SME to help expand and polish it, please contact me off-list and I'll get you a current draft. Thanks in advance. Cheers, ~Chris -- @ChrisGrundemann http://chrisgrundemann.com

Managing free pairs to prevent DSL sync. loss
by Anurag Bhatia 17 Jul '12

17 Jul '12

Hello everyone. I am having some very bad time due to my ISP's poor last mile (in India). DSL is loosing sync. consistently and this time problem seems quite interesting so I though to ask how ISPs across world managing it. Problem is high attenuation & low SNR because of "lot of free pairs" in the cable. My connection is coming from something like 100 pair > 50 pair > 20 pair > 5 pair. Now 100 pair has less then 30 active lines but based on testing it seems like at 100 pair DP there's very low noise and everything is pretty good (usual BSNL pillars in India have 100 pair terminations). Next 20 pair has just 4 active lines (and 16 free lines causing issues for those 4 working lines) and at the end my line comes from 20 > 5 with only one (which is my) line active on one of 5 pairs. Now argument of my ISP (BSNL) is that due to excessive number of free pairs, they are causing huge noise and they likely need to reduce these DP's by putting 1-2 line wire from my home till 100 pair pillar termination (which is down in other street and so needs effort in digging and putting new wire). But I just never heard about this problem anywhere else. Do DSL providers really suffer due to free pairs? Assuming other pairs are all crossed/shorted, can they still produce significant noise in other working lines? Also, what exactly was "bonding" used by AT&T in US? I thought it was actually making use of free pairs, bonding them together and having more bandwidth for end user, isn't it? If someone can pass me some detailed whitepaper or document explaining about this noise, it will be very much helpful. Thanks. -- Anurag Bhatia Web: anuragbhatia.com Skype: anuragbhatia.com Linkedin <http://in.linkedin.com/in/anuragbhatia21> | Twitter<https://twitter.com/anurag_bhatia>| Google+ <https://plus.google.com/118280168625121532854>
