Subject: Re: How our young colleagues are being educated.... Date: Fri, Dec 26, 2014 at 02:56:40AM -0500 Quoting William Herrin (bill@herrin.us):
In the real world you often assign a /32 to a loopback address on each router and make all of the serial interfaces borrow that address (ip unnumbered in Cisco parlance) which wastes no addresses.
Why would you want to waste 79228162514264337593543950336 addresses on a loopback? More seriously, why does this discussion only briefly mention IPv6? Every client comes with it (aggressvely) enabled -- it is there despite the fat / happy parts of the networking community sitting on their legacy space and laughing at Asia. I've had, as mentioned earlier, a "cisco graduate" as intern and then colleague for a year now. He's a fast learner, and that was needed. No v6. Not much MPLS. No ISIS. Barely eBGP. No iBGP, especially not in conjunction with a link-state IGP. Lots of RIP, Flame Delay and EIGRP. There are two problems; * The academic community is either outdated or married to a vendor-specific course -- and that marriage is not very academic, IMNSHO. Academia must be vendor agnostic. * The vendor courses are too enterprisey, and an outdated enterprise at that. There is no course in "running a sensible chunk of the Internet". And this in a world where the largest innovation the last 5 years is abstraction (as in virtualisation and to some extent SDN). Not in protocols. Should be reasonably easy to keep up. -- Måns Nilsson primary/secondary/besserwisser/machina MN-1334-RIPE +46 705 989668 So this is what it feels like to be potato salad
