Improving BGP Convergence without Tweaking BGP Timers

One of the perks of my online courses is the lifetime access to course Slack team, and you’d amazed by the variety of questions asked there. Not so long ago I got one on BGP timers:

The BGP timers I’m using in my network are 5 and 15 seconds, and I am not sure if it's a good practice to reduce them even more.

You should always ask yourself this set of questions before tweaking a nerd knob:

NFD16 First Impressions

Getting bored sitting at San Jose airport waiting for Vagrant to update guest additions in my Ubuntu VM (first item on my to-do list: prepare final version of material for next week’s Docker workshop), so here are my very first impressions of Networking Field Day 16 presentations we’ve seen in the last three days.

As always, there were great presentations, good presentations, … and a few that are best forgotten. I won’t mention those.

Open-Source Networking Textbook

A month ago I told you how dr. Olivier Bonaventure starts his networking course with IPv6. But there’s more: the full textbook for the undergraduate course (Computer Networking: Principles, Protocols and Practice) is open-sourced and available (in source form) on GitHub.

You might wonder why I’m so enthusiastic, so let me tell you another story…

New theme on blog.ipspace.net

You might have noticed that my blog looks a bit different than it did a few hours ago thanks to fantastic work by Nils & Mathias from Strandrover.Agency (and a bit of homegrown blogger template hacking). We tested all functionality we could think of, if we missed something, please write a comment (they still work ;).

When reporting a problem, please tell me what browser (and browser version) you're using and whether you're using a web proxy (like Cisco Web Security Appliance).

New in Ansible for Networking Engineers Online Course

Plenty of new stuff was added to the Ansible for Networking Engineers online course and webinar since the last update.

Fun things first: I needed adjustable check mode behavior and change tracking in some playbooks, and documented these features in two new videos (online course and webinar).

Intent-Based Hype

It all started with a realistic response I got to my automation and orchestration blog post (here’s a unicorn-driving-a-DeLorean one in case you missed it):

Maybe you could also add the "intent-based network" which is also not so far from orchestration?

It got me thinking. The way I understand intent-based whatever, it’s an approach where I tell a system what I want it to do, not how to do it.

Automation Tools in Building Network Automation Solutions Online Course

A network engineer interested in attending the Building Network Automation Solutions online course sent me this question:

Does the course cover only Ansible, or does it also cover other automation tools like Python?

The course focuses on how you’d build a network automation solution. Selecting the best tool for the job is obviously one of the major challenges, and so one of the self-study modules describes various automation tools and where you could use them to build a full-blown solution.
