BRKDEV-1368

Environment Setup

Follow these instructions to standup the demo and code environment.

Pre-reqs
- Python 2.7 and Python 3.6
  - pip and virtualenv
If you haven't already, clone down this repository to your local workstation.
```
git clone https://github.com/CiscoDevNet/BRKDEV-1368.git
```
Change into the code repository directory.
```
cd BRKDEV-1368
```

Setup Python Virtual Environment

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

Reserve an instance of DevNet Sandbox - Multi-IOS Test Network. Pick None as the Virl Simulation before reserving. This will start the lab with NO topology loaded in VIRL, we'll be starting our own.

It will take about 10 minutes for the lab to fully spin up.
Once your lab is ready, use the VPN credentials you recieve via email, or find in the OUTPUT box in the Sandbox portal to connect to your lab.
We will use the Python package virlutils to start the lab. If you don't have it installed already, go ahead and do so now.

Note: This guide assumes a basic knowledge of Python and doesn't explicitly state to use a virtual environment, or a version of Python to use. Any recent version of Python and common working environment should work.
```
pip install virlutils
```

Verify that your lab and virlutils is working.

# Check what version of VIRL is loaded (verify you can talk to server)
virl version

# Check if any simulations are running
virl ls --all

Output

$virl version
virlutils Version: 0.8.8
VIRL Core Version: 0.10.37.32

$ virl ls --all

If any simulation other than ~jumphost is running, stop it with the following command.
```
virl down --sim-name {SIMULATION_NAME}
```

Jump into the demo directory where the topology file is located.
```
cd demo
```

Start a simulation for this lab.

virl up

Output

Creating default environment from topology.virl

It will take several minutes for the simulation to fully start, you can monitor it with the following command - waiting for all devices to show REACHABLE
