# Start

Launch the lab by using the following commands on your containerlab machine:

```
cd jncia-junos-labs/
containerlab deploy -t switched-lan/switched-lan.clab.yml
```

The nodes will take a couple minutes to launch. You can use the command **docker container ls** to see if they are ready yet.

When they are not ready yet, you will see **(health: starting)** under STATUS.

```

```

You will be able to change between labs without having to re-launch the topology. Each lab will provide instructions on loading the proper starting config. This saves a lot of time when labbing.

When you are done labbing, use the following command to bring it down:

```
containerlab destroy -t switched-lan/switched-lan.clab.yml
```
