Self Hosted
===========

The installation process listed below is from running this lab on my own Linux laptop with Pop_OS (Ubuntu base). You may have to alter some of the commands to get
gns3 installed/started, but after that we'll only be working with the gns3 UI.

* install `gns3`_

.. _gns3: (https://www.gns3.com/software/download)

* set `permissions`_ for packet tracer (Linux)

.. _permissions: https://askubuntu.com/questions/748941/im-not-able-to-use-wireshark-couldnt-run-usr-bin-dumpcap-in-child-process

* download the FRR `image`_

.. _image: https://www.gns3.com/frr


You'll now need to add the image as an applicance from the UI.

Configurations provided in the hosted lab. You'll need to add these configurations to the routers based on name below. This will *catch you up* to users of the hosted 
lab.

Please see next section for starting routers and accessing their console.

With these configurations now in place, you are ready to begin the lab. All routers should have all interfaces assigned now and even a few are set up to form BGP peers.
