NYC & Philly Metro rack stack and config
by Daniel Corbe 28 Apr '16

If anyone in the NYC and Philly metro areas want to make a few extra bucks, contact me off list. I need someone to drop an initial config on some brocade routers and run some cabling. Best, Daniel

IPv6 prefix from T-Mobile USA used but not announced in BGP (2607:7700::/32)
by Baptiste Jonglez 27 Apr '16

27 Apr '16

Hi, While doing statistics on the participants of a public DHT, I was surprised to see some IP addresses that are not present in the DFZ: 2607:7700:0:25::4e00:605b 2607:7700:0:25::4e25:8ce8 2607:7700:0:25::c808:db2c 2607:7700:0:4::3294:6683 2607:7700:0:4::4c09:4d39 2607:7700:0:4::5985:87d1 2607:7700:0:4::5d7d:3df8 All those IP are in 2607:7700::/32, allocated to T-Mobile USA but never announced: https://stat.ripe.net/2607%3A7700%3A%3A%2F32#tabId=at-a-glance What could explain their usage in an application? Some form of address translation? Maybe these addresses have been used as source address in outgoing packets, which would indicate IPv6 tests in T-Mobile? (but obviously, nobody is able to answer such packets). Baptiste

GeoIP database issues and the real world consequences
by Chris Boyd 27 Apr '16

27 Apr '16

Interesting article. http://fusion.net/story/287592/internet-mapping-glitch-kansas-farm/ An hour’s drive from Wichita, Kansas, in a little town called Potwin, there is a 360-acre piece of land with a very big problem. The plot has been owned by the Vogelman family for more than a hundred years, though the current owner, Joyce Taylor née Vogelman, 82, now rents it out. The acreage is quiet and remote: a farm, a pasture, an old orchard, two barns, some hog shacks and a two-story house. It’s the kind of place you move to if you want to get away from it all. The nearest neighbor is a mile away, and the closest big town has just 13,000 people. It is real, rural America; in fact, it’s a two-hour drive from the exact geographical center of the United States. But instead of being a place of respite, the people who live on Joyce Taylor’s land find themselves in a technological horror story. For the last decade, Taylor and her renters have been visited by all kinds of mysterious trouble. They’ve been accused of being identity thieves, spammers, scammers and fraudsters. They’ve gotten visited by FBI agents, federal marshals, IRS collectors, ambulances searching for suicidal veterans, and police officers searching for runaway children. They’ve found people scrounging around in their barn. The renters have been doxxed, their names and addresses posted on the internet by vigilantes. Once, someone left a broken toilet in the driveway as a strange, indefinite threat. --Chris

NCS5K?
by Chris Welti 27 Apr '16

27 Apr '16

According to some slides from a russian cisco connect event, the upcoming small-size NCS 5501 and NCS 5502 will support 1M+ FIB and 50ms per port buffers. Seem to be killer boxes. 48x100GE in 2RU with large FIB & buffers? Loving it already. I wonder what prices will look like for those. With Google Translate: NCS 5501 • 800 Gbps @ 430 watts • 40 x SFP + 1G / 10G + 4 x QSFP28 100G • 1RU • Intel Broadwell CPU 8Core @ 1.6GHz • Dimensions WxDxH 444mm x551mm x 44mm • External TCAM for more FIB, large buffers (~ 50 ms) • 1-2M IPv4 FIB • The same set of features as a modular • FCS in IOS XR 6.1.1 NCS 5502 • 4.8 Tbps 100G @ ~ 2200 W • 48 x QSFP 28 or QSFP + optics • 2RU • Intel Broadwell CPU 12Core @ 1.6GHz • 8 ASIC packet processing • Integrated FIA • External FIB TCAM for more • Large buffers (~ 50 ms) • 1-2M IPv4 FIB • The same set of features as a modular • FCS in IOS XR 6.1.1 On Mon Jan 25 18:01:41 EST 2016, Phil Bedard <philxor at gmail.com> wrote: > My guess is you will see something from Cisco similar to the PTX1K in the > NCS 55XX series but it will be more expensive than the 500X series.

Firewall list recommendations (config conversion options)
by b f 25 Apr '16

Hi list, Could any one recommend any firewall related mailing lists? Looking for options on converting a large amount of Fortinet rules to Checkpoint. Ultimately converting the entire configuration to Checkpoint would be nice. Thank you for any advice you can provide. Respectfully, Ed

As a SP, what is your standard CoS configuration on JunOS?
by Sean Kennedy 25 Apr '16

25 Apr '16

NANOG, I realize that every SP handles marking and queueing/scheduling differently, but I am curious to see other provider's 'standard' config for QoS that is deployed on the JunOS platform. What config do apply to all your ingress interfaces for classification? How are your core link schedulers configured? What kind of remarking do you do (specifically on packets arriving on internet-facing interfaces)? If you have a converged network carrying both internet and carrier-eth/transport traffic, how do you handle guaranteeing bandwidth to the carrier eth services? Thank you, Sean
