IPv6 Management
by Justin Wilson 23 Aug '18

23 Aug '18

We were having an interesting debate on IPV6 management on layer2 devices. Does anyone have a best practice document they have seen for utilizing v6 Management addresses? I know Cisco has some extensive documentation on using v6 on their wireless products. I know everyone has thoughts so am interested in any best practices which have been presented to the community. I haven’t worried about management access on layer2 devices, as long as the layer2 devices can pass any cast, multicast, and other things v6 needs. However, I could see why you would want v6 management addresses. And go…. Justin Wilson j2sw(a)mtin.net www.mtin.net www.midwest-ix.com

I thought about sending another 'dust off your DR plan' for those networks doing business in the AP region that have stuff here, but if they didn't on the last one they wouldn't on this one, either. :-) It's an M (>110 MPH) until the Big Island on Thur and then goes down to a regular hurricane Friday when it hits Maui and Oahu Friday. http://www.prh.noaa.gov/cphc/tcpages/?product=5day_cone_with_line_and_wind&… http://weather.hawaii.edu/satellite/jsanim.cgi?res=4km&chnl=ir&domain=nep&p… scott

Re: NANOG Digest, Vol 127, Issue 16

- PRTG, it's realy easy to configure. Most of the senssors are SNMP of: traffic/ping/cpu/memory and some senssors for servers like DNS and Radius, etc. - Zabbix, there's 2 things that made us use Zabbix, the first one it's Zabbix Proxy, since the network it's geographical distribuited we need a tool that provides us monitoring from another places with a low price. And LLD that i use for monitoring BGP/OSPF sessions and prefix. - Elastiflow - For Syslog we use Graylog, that i recomend, it's a excelente tool for monitoring syslog messages and there's a lot of features such as extractors, streams and alerts. I think that PRTG it's kind expensive solution ( if you buy the license ), but provides a easy way to monitor a lot of things. Just one thing, if your license expires your are no able to update your software and if you want to buy the license for upgrade, the days without the license counts as negative days, i never seen that before, like, if you don't update the license for 1 year and bought the 3 years lisence, you will got 2 years of support and upgrade.

optical circulator as a bidirectional one fiber solution
by Baldur Norddahl 22 Aug '18

22 Aug '18

Hello There is a lack of bidirectional one fiber (BIDI) options for 40G and 100G optics. Usually BIDI is implemented using two CWDM wavelengths, one for tx and one for rx. However there is also a lack of CWDM and DWDM options for 40G and 100G. Would it be possible to use an optical circulator like this one (customized to 1310 nm)? https://www.fs.com/de/en/products/33364.html Combined with a traditional two fiber 1310 nm 10 km 40G QSFP module like this: https://www.fs.com/de/en/products/24422.html The link distance would be 5 km. The optical circulator separates tx and rx by the direction the light travels in. It would work even though both directions use the same wavelength. There will likely be some reflection but hopefully attenuated enough that it is regarded as background noise. Has anyone done this? Any reason it would not work? Regards, Baldur

Pybatfish - Open source network validation SDK
by Ratul Mahajan 22 Aug '18

22 Aug '18

Hey, folks - Since many of you build and use tools for network validation, I wanted to share a quick announcement. We just released Pybatfish <http://github.com/batfish/pybatfish>, a Python SDK for Batfish. As you may know, Batfish is an open source framework for deep (semantic) validation in multi-vendor networks (which we presented at NANOG65 <https://www.youtube.com/watch?v=sKApcGY6MxQ>). Pybatfish will make it easy for you to leverage the power of Batfish and to embed validation in your testing/automation pipeline. Getting started is easy: Check out the Jupyter notebooks on our github page (or corresponding videos <https://www.youtube.com/channel/UCA-OUW_3IOt9U_s60KvmJYA>), or ping us on Slack <https://join.slack.com/t/batfish-org/shared_invite/enQtMzA0Nzg2OTAzNzQ1LTUx…> . Cheers.
