H3C Technical List

Hey all, Anyone know of a Mailing list like Cisco-NSP/Juniper-NSP for HP/H3C equipment? I have some questions regarding some H3C Switch spanning-tree behaviour, but I can't find anyone to ask. The couple of lists on puck have had almost no traffic for a ling time. Thanks all. * * *Skeeve Stevens, CEO - *eintellego Pty Ltd skeeve(a)eintellego.net ; www.eintellego.net Phone: 1300 753 383; Cell +61 (0)414 753 383 ; skype://skeeve facebook.com/eintellego ; <http://twitter.com/networkceoau> linkedin.com/in/skeeve twitter.com/networkceoau ; blog: www.network-ceo.net The Experts Who The Experts Call Juniper - Cisco – IBM - Brocade - Cloud ----- Check out our Juniper promotion website for Oct/Nov! eintellego.mx Free Apple products during this promotion!!!

What is BCP re De-Aggregation: strict filtering /48s out of /32 RIR minimums.
by Ben S. Butler 22 Nov '12

22 Nov '12

Hi, I am hoping for a bit of advice. We are rolling out IPv6 en mass now to peers and I am finding that our "strict" IPv6 ingress prefix filter is meaning a lot of peers are sending me zero prefixes. Upon investigation I determine they have de-agregrated their /32 for routing reasons / non interconnected islands of address space and in consequence advertise no covering /32 route. The RIR block that the allocation is from is meant to have a minimum assignment of /32. From: http://www.space.net/~gert/RIPE/ipv6-filters.html We get: ipv6 prefix-list ipv6-ebgp-strict deny 3ffe::/16 le 128 ipv6 prefix-list ipv6-ebgp-strict permit 2001:500::/30 ge 48 le 48 ipv6 prefix-list ipv6-ebgp-strict deny 2001:db8::/32 le 128 ipv6 prefix-list ipv6-ebgp-strict permit 2001::/32 ipv6 prefix-list ipv6-ebgp-strict permit 2001::/16 ge 35 le 35 ipv6 prefix-list ipv6-ebgp-strict permit 2001::/16 ge 19 le 32 ipv6 prefix-list ipv6-ebgp-strict permit 2001:0678::/29 le 48 ipv6 prefix-list ipv6-ebgp-strict permit 2001:0c00::/23 ge 48 le 48 ipv6 prefix-list ipv6-ebgp-strict permit 2001:13c7:6000::/36 le 48 ipv6 prefix-list ipv6-ebgp-strict permit 2001:13c7:7000::/36 le 48 ipv6 prefix-list ipv6-ebgp-strict permit 2001:43f8::/29 ge 40 le 48 ipv6 prefix-list ipv6-ebgp-strict permit 2002::/16 ipv6 prefix-list ipv6-ebgp-strict permit 2003::/16 ge 19 le 32 ipv6 prefix-list ipv6-ebgp-strict permit 2400::/12 ge 19 le 32 ipv6 prefix-list ipv6-ebgp-strict permit 2600::/12 ge 19 le 32 ipv6 prefix-list ipv6-ebgp-strict permit 2610::/23 ge 24 le 32 ipv6 prefix-list ipv6-ebgp-strict permit 2620::/23 ge 40 le 48 ipv6 prefix-list ipv6-ebgp-strict permit 2800::/12 ge 19 le 32 ipv6 prefix-list ipv6-ebgp-strict permit 2a00::/12 ge 19 le 32 ipv6 prefix-list ipv6-ebgp-strict permit 2801:0000::/24 le 48 ipv6 prefix-list ipv6-ebgp-strict permit 2c00::/12 ge 19 le 32 ipv6 prefix-list ipv6-ebgp-strict deny 0::/0 le 128 I have peers in 2a00::/12 that are advertising me /48s without the /32 assigned to them. While this has been a problem in IPv4 land in the past with some people de-aggregating a /19 to regional /24s with no covering route because of no backbone. What should we be doing in IPv6 land as I suspect this may become a bigger problem than it ever was in IPv4. I can adopt the view, well you should, so I'm going to filter, and they can say well that's not practical, we have a /32 and we advertise a /48 at each individual internet exchange. RIRs policy wont allocate us a lot of separate /48s from an appropriate block. Aggregation argues you shouldn't de-aggregate. We might as well start off as we mean to go along and try not to pollute the v6 route table with all the rubbish that is in the v4 one. So what is the "best" answer. 1> Don't advertise islands of space under assignment minimum, without providing a covering aggregate route? 2> Don't use strict filters, they don't work well and de-agragegation with IPv6 is going to be a problem? 3> Don't use filters, generate it from an IRR? Given there is no "right" answer what is considered to be the best fit one? Kind Regards Ben

NTP Issues Today

Hello, Did anyone else experience issues with NTP today? We had our server times update to the year 2000 at around 3:30 MT, then revert back to 2012. Thanks, Van

re: 25Mbps vs 4 Mbps
by Nick Olsen 21 Nov '12

It's all about if the bandwidth is there to use. I'm sure every youtube caching server has a connection which exceeds 4Mb/s. How does a faster connection help? It allows the video to fill the buffer faster. Allowing for smoother playback on less bandwidth consistent circuits. Do you need it really if your video source is under 4Mb/s? In a perfect scenario, No. Now, That's youtube. Using Netflix as an example. I can start streaming a movie. And it'll pull 50-60Mb/s for about 20 seconds, And it's playing HD quality almost immediately. Where on a slower connection it may not switch to HD until its filled its buffer more.

This means that the internet connection that i take from my service provider only affects the last mile -- from my home network to my service providers first access router. Given this, would one really see a 6 times improvement in a 25Mbps connection over a 4Mbps connection? I assume that the service providers rate limit the traffic much more aggressively in a 4Mbps connection. But this would only matter if the traffic from my youtube server is greater than 4Mbps, which i suspect would be the case. The question then is that how does going for a higher BW connection from the service provider help? Glen

Road Runner route server, AS20001 / 7843
by David Hubbard 21 Nov '12

Anyone know of a route server on either of those AS's? Attempting to troubleshoot an issue that they're blaming on a fiber cut in Texas so I have to get more useful evidence to get it escalated. Thanks, David

Fiber terminations -- UPC vs APC
by Jeff Kell 21 Nov '12

21 Nov '12

Looking for some guidance/references on the use of UPC versus APC terminations on fiber cabling. Traditionally we have done all of our fiber plant targeting data usage with UPC connectors. We are also looking at proposals for fiber distribution plant for video, and the possibility of using some of the existing fiber plant for that purpose; as well as any new fiber plant that gets installed for video potentially as data. The video folks are set, determined, and insistent that they need APC terminations. All data references I have found preach UPC. Cisco's SFP reference page even states (in bold): > *Note:* Only connections with patch cords with PC or UPC connectors are supported. > Patch cords with APC connectors are not supported. All cables and cable assemblies > used must be compliant with the standards specified in the standards section. So are we doomed to having physically separated fiber plants with suitable connectors / jumpers dedicated to video? Anyone been down this snaky looking path? Jeff
