Collection of useful, relevant or just fun places on the Internets for 6th August 2013 and a bit commentary about what I’ve found interesting about them:
Github – bfontaine/rfc – Read RFCs from the command-line – I’ll be playing with this. Not sure it will work for me but someone else might like it.
rfc is a little tool written in bash to read RFCs from the command-line. It fetches RFCs and drafts from the Web, then caches them locally, so each document is fetched only once.
Now, I love OpenFlow and SDN as much as the next network geek, and I think it’s about as disruptive and game changing as the next guy. However, IPv6 is next. There. I said it. We need it. Hey, OpenFlow 1.3 supports it so there is your tie in. We’re out of v4 for the most part and, lets be honest, NAT is a freaking abomination. It’s not a solution to anything other than over complicating a transit path with translational mappings.
Temper Your MacGyver Streak « ipSpace.net by @ioshints – Love hearing about other peoples experiences so that I can learn from them
In my case, I had to go with 20 EIGRP processes because the customer needed MPLS/VPN-like solution years before MPLS/VPN was invented (and yes, we migrated them to MPLS/VPN in the meantime). The customer had a well-coordinated IP address space, so I might have used an alternative design using BGP communities and selective route advertisements, but they insisted on using Frame Relay instead of a routed network (where we’d use the core routers as PE-routers), leaving the EIGRP mess as the only viable option.
TRILL’s Hidden Cost | Next-Generation Data Center – Tom Hollingsworth writes at Network Computing about the impact on innovation when software feature licensing effectively prevents adoption of new technologies like TRILL.
Why not reduce or outright eliminate the licensing requirement for TRILL or TRILL-like features to hasten the demise of STP? The response was nothing if not predictable: “We have demo licenses to allow customers to try these features out and see how they can benefit.” Anyone ever redesigned an entire network for the sake of enabling a time-limited demo feature?
Westcliff High School switches to Linux | opensource.com – Interesting and balanced look at a school that has switched to using Linux on all desktops. (Sad that I have to say “balanced”). Overall, its a win for Linux.
Around a year ago, a school in the southeast of England, Westcliff High School for Girls Academy (WHSG), began switching its student-facing computers to Linux, with KDE providing the desktop software. The school’s Network Manager, Malcolm Moore, contacted us at the time. Now, a year on, he got in touch again to let us know how he and the students find life in a world without Windows.
Python for Network Engineers – What it says. Lots of useful code snippets and advice.
Cisco EIGRP OTP Connects Networks Across Provider Infrastructure | – Ethan Banks with a deep dive on Cisco EIGRP OTP technology. This is a really interesting development that combines EIGRP and LISP to solve a real problem. Get excited about this.
Cisco Systems has been hoisting the EIGRP flag up high of late. Enhanced Interior Gateway Routing Protocol–a routing protocol, of all things (yawn)–wouldn’t seem like anything to get too excited about, what with all the hoopla surrounding software-defined networking, overlays and network virtualization. And yet Cisco is clearly committed to EIGRP.
