![Cisco Nexus 9000v OSPF p2p topology](network-diagram.png)

This Vagrant project demonstrates a single area OSPF point-to-point network topology with three Cisco Nexus 9000v nodes.

## Ingredients

  * [Vagrant](https://www.vagrantup.com)

  * [vagrant-libvirt](https://github.com/vagrant-libvirt/vagrant-libvirt)

  * [Cisco Nexus 9000v Vagrant box](https://github.com/mweisel/cisco-nxos9kv-vagrant-libvirt)

  * [Python](https://www.python.org) >= 3.5

  * [Ansible](https://www.ansible.com) >= 2.9

## Prerequisites

01\. Add a DHCP reservation for each Cisco Nexus 9000v management interface.

Refer to [Controlling Vagrant Box Management IP](https://codingpackets.com/blog/controlling-vagrant-box-management-ip) for more information.

02\. Set the SSH client configuration for the Cisco Nexus 9000v nodes.

Refer to [Vagrant SSH Config Trick](https://codingpackets.com/blog/vagrant-ssh-config-trick) for more information.


$ tail -n +1 $HOME/.ssh/config $HOME/.ssh/vagrant.d/sshconfig

## Steps

01\. Clone this GitHub repo and _cd_ into the `ansible` subdirectory.


$ git clone https://github.com/mweisel/cisco-nexus-ospf-p2p

$ cd cisco-nexus-ospf-p2p/ansible



02\. Create a Python virtual environment.


$ python3 -m venv .venv



03\. _Activate_ the Python virtual environment.


$ source .venv/bin/activate



04\. Update the `pip` and `setuptools` Python packages.


$ pip install -U pip setuptools



05\. _Reactivate_ the Python virtual environment.


$ deactivate && source .venv/bin/activate



06\. Install the `ansible` and `paramiko` Python packages.


$ pip install -r requirements.txt



07\. _Reactivate_ the Python virtual environment.


$ deactivate && source .venv/bin/activate



08\. Instantiate the Cisco Nexus 9000v nodes.


$ vagrant up --no-parallel



09\. Run the Ansible playbook to configure the Cisco Nexus 9000v nodes.


$ ansible-playbook set-config.yml



10\. Verify the configuration.


$ ssh nx02




nx02# show ip ospf neighbors

nx02# show ip ospf route

nx02# run bash for lo in 1 3; do ping -c5 192.0.2.${lo}; done
