Historical routing question
by Hank Nussbacher 12 Apr '18

12 Apr '18

While giving a routing lecture today someone asked me "Why was eBGP assigned an administrative distance of 20 which is better than OSPF's administrative distance of 110. What was the logic behind that decision?" I was unable to think of an answer. Ideas? Thanks, Hank

Quickscan routing security
by Ad Bresser 03 Mar '18

03 Mar '18

Dear routing-wg, Last year I composed a quickscan on routing measures to increase the security of the Internet. You can download it at: http://startupinc.nl/wp-content/uploads/2017/10/20171027-Quickscan-on-routi… In order to improve the overview I also created a Github version. Please add your additions here: https://github.com/AdBresser/measures-to-increase-IP-security Hope this helps in improving the IP security of the Internet. Kind regards, Ad Bresser PS For sharing in your LinkedIN network a version of the quickscan is available on LinkedIN: https://www.linkedin.com/pulse/measures-increase-routing-security-internet-… (likes are also appreciated 😉 )
