Automating the deployment of a BGP fabric with Nornir version 3 (You can go back to nornir version 2 by using git checkout 80bfa9dcb5b4c25d83cabc8a44d1b822e5c779bb)
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).
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.shThis 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.
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.
