+1 on the freesd-or-linux. with say a Garmin GPS-18x or whatever timing puck. Have an intern or junior tech tackle it as a learning exercise. The time geeks on comp.protocols.time.ntp seem to favor low-power Soekris hardware (http://soekris.com/) for stratum-1s. You need RS232 serial to get decent PPS; USB introduces tons of jitter. If you have to have something pre-integrated and soon, I'd look at Meinberg: http://www.meinberg.de/english/products/index.htm#network_sync -- RPM

ipv6 book recommendations?
by David Hubbard 27 Jun '12

27 Jun '12

Does anyone have suggestions on good books to really get a thorough understanding of v6, subnetting, security practices, etc. Or a few books. Just turned up dual stack with our peers and a test network but I'd like to be a lot more comfortable with it before looking at our customer network. Thanks, David

please helpconfederation and ibgp question
by Deric Kwok 26 Jun '12

26 Jun '12

Hi all I would like to ask questions aboutconfederation and ibgp We know confederation from nanog achieve 101,102 and setup lab. bgp and ibgp can work properly but not sure we are doing right. We have quesions 1/ for the annoucing networks, do we have to announce it in border routers? eg: border routers. 66.59.128.0/22 but all ibgp routers are already announcing networks individually in ibgp Routers eg: Router A: 66.59.128.0/24, Router B: 66.59.129.0/24, Router C: 66.59.130.0/24, Router D: 66.59.131.128/25 In our labs, it can work. but we would like to know the setting is correct. or any announcing overlapping when announcing in broder Router and all individual ibgp routers 2/ But if it is not right to announce /22 in broder routers, let Router A,B,C, D announce it in 4 separate networks. ls it ok too? in the lab, the bgp can work too. but i read the bgp doc that it prefers us to announce it in /22 instead of 4 seperate one? 3/ in the border routers, we take out some ip from network 66.59.131.0/24 (eg: 66.59.131.0/28, 66.59.131.16/28) to interconnected to Router A, B, C and D We don't know which one is good for use in bgp configuration redistributed connected or network 66.59.131.0/28 network 66.59.131.16/28 If using network command "network 66.59.131.0/28, network 66.59.131.0/28" to let communicate between ibgp, there might have overlapping too as we already announcing 66.59.128.0/22. in the border router, there might have network 66.59.128.0/22 network 66.59.131.0/28 network 66.59.131.16/28 ls the command "redistributed connect" better? but this is border Router. We concern it will effect the upstream using redistributed connect Please help Thank you so much

[NANOG-announce] Appointment of Dan Golding as Board Member
by Sylvie LaPerriere 26 Jun '12

26 Jun '12

NANOG Colleagues, The Board has met last Friday June 22 and appointed Dan Golding as the replacement board member until the next election. He will join our next Board on July 6. We would like to thank everyone who submitted their candidacy for this interim. Your desire to serve is encouraging. We had previously announced that we would communicate this appointment on June 22. The delay is due to our desire to communicate personally with all that were not selected first. We trust you understand. Welcome Dan! Sincerely, -- Sylvie LaPerriere NANOG Chair - www.nanog.org _______________________________________________ NANOG-announce mailing list NANOG-announce(a)nanog.org https://mailman.nanog.org/mailman/listinfo/nanog-announce

Collecting flows at an IXP
by Graham Beneke 26 Jun '12

26 Jun '12

Hi All I'm busy doing some digging to find a solution for collecting layer-2 flows data on a medium sized IXP. All we have at the moment is some MRTG graphs and we're trying to get a better view into IPv4 vs IPv6, src and dst MACs, packet sizes and also perhaps port & protocol trends. I found Richard A. Steenbergen's NANOG 39 presentation and not much since then. Is it still correct that Cisco does not support sFlow? Are you able to get the same kind of useful data using Netflow v9? Which FOSS flow collectors do an decent/adequate job at crunching about 10Gbps worth of flows and presenting it in a useful way? Thanks -- Graham Beneke

Cisco ASR router performance specs
by Andrey Khomyakov 26 Jun '12

26 Jun '12

Hi all, Could you point me into the right direction, please, on where one would find different performance ratings for Cisco routers other than talking to my SE (who is on PTO right now). My understanding is that Cisco does not publish this info. How do folks research that kind of stuff? For example, right now I want to find out how many DMVPN tunnels a given model of an ASR will support and what kind of throughput I can count on with that enabled. Thanks in advance for answers --Andrey
