Abstract all the Things

17 June 2016    automation networking ops 

A couple of weeks ago I made this presentation/demo about abstractions for network operations titled “Abstract all the Things”. The idea was to show how templating is good but not good enough, sometimes you have to step back and focus on the goal and not on how to get there. Well, if you are interested in the topic you can find below the video, the link to the templates and to the github repo where you can find all the code I used for the demo.


OpenConfig + NAPALM soon...

06 May 2016    ops automation networking napalm 

The other day I talked with Rob Shakir who has been working very closely with OpenConfig and we came up with the idea of trying to add OpenConfig support to NAPALM.

The idea was that a network driver would translate unsupported models to native commands while models supported by the device would be sent via native mechanisms (gRPC, NETCONF, etc.). That would allow people to start using OpenConfig as NAPALM would serve as a transition mechanism.

So, after Rob sent me an example on how to use pyangbind, which he also wrote by the way, I put together a POC. It is very cool to see that thanks to pyangbind adding OpenConfig to NAPALM was really a piece of cake. Open Source for the win!


ChatOps Demo for Networking ansible + napalm + stackstorm + slack

30 March 2016    ops automation networking 

I have been working on a project to automate all things network related. Not only provisioning new stuff but operations as well. I am not going to tell you about the benefits of automation, everybody should know by now.

However, when talking about operations it is important to note that not all operations can be automated but all operations can be abstracted. What I mean with that is that if you are peering with someone you still have to perform some action so your system knows who the new peer is, their IP address, their AS and where are you going to peer with them. However, the operator doesn’t need to know that it has to go to the inventory system to add the new peer, then go to the IPAM system to insert the required information and finally configuring the peer on the router. You could abstract that entire repetitive and error prone workflow with a single command: add peer in=bma ip=10.0.0.1 as=65100.

Creating your own Vagrant boxes How to create a box with IOS-XR

14 January 2016    automation networking 

Creating vagrant boxes is fairly easy and very useful. Using vagrant boxes that are publicly available is preferred as it makes easier to share your environment but in some cases you might want to tweak a bit an existing box or you might want to create your own because there is no box available for a particular virtual appliance.

As mentioned previously, creating a vagrant box is very simple, you only have to create a VM on your provisioner and export it as it is. To show you how to do it we will create a vagrant box for IOS-XR. Before we start you will need the following:

  • Vagrant, of course. For more information check this post.
  • Virtualbox.
  • An OVA or a VMDK for IOS-XR. I am using iosxrv-k9-demo-5.3.0.ova.
