Wow thanks for sharing both of these. Anycast can be "black magic" sometimes, and the more that is known about it by operators the better. I'm somewhat surprised that ECMP I've done a little poor-mans anycasting within a network by simply using OSPF and some /32's. Had IPv4 space not been at such a premium when I got into the game, I would have definitely attempted to get a larger block so that I could anycast a /24 of it. :-( Theodore Baschak - AS395089 - Hextet Systems https://ciscodude.net/ - https://hextet.systems/ http://mbix.ca/ On Mon, Dec 12, 2016 at 1:27 PM, chris <[email protected]> wrote:@natmorris did something similar 18 months to 2 years or so ago too video below from uknof 30 .. https://youtu.be/itEtjsauwFQ Sent from Samsung Mobile on O2 -------- Original message --------From: Franck Martin via NANOG < [email protected]> Date: 12/12/2016 18:39 (GMT+00:00) To: NANOG < [email protected]> Subject: Build an anycast network on a shoestring This is quite a nice write up by a colleague of mine: https://www.linkedin.com/pulse/build-your-own-anycast- network-9-steps-samir-jafferali
