Automating the deployment of a BGP fabric with Nornir

This basically reproduce exactly the fabric done here but using Nornir: FullyAutomatedBGPfabric

Hence, this deployment is aimed at debian-based Linux targets only (including Cumulus Linux).

Prerequisites

On a recent system, you should be good to go simply with pip install -r requirements.txt

However, Nornir needs at least python 3.6 and there are still a whole lot of devices using older versions.

If you have an older python version (or if you are using CITC), you should use this to install python 3.6.3 and all the dependencies to use Nornir :

curl -LO https://raw.githubusercontent.com/jpmondet/norniring-bgpfabric/master/resources/add-compatible-python.sh ; chmod u+x add-compatible-python.sh ; source add-compatible-python.sh

This use pyenv on one specific directory and a virtualenv so it should not mess up with the rest of your system.

NOTE: The ssh keys are already distributed on CITC so this is not handled by the script.

Deploying the Fabric

If you are on CITC, this is pretty straightforward : python deploy_network.py

Elsewhere, you'll have to update the inventory.

This repo uses an Ansible's style inventory so you have to update the hosts file and the host_vars and/or group_vars directories.
