Juniper ZTP/Homer

Goal

In this Tutorial, we are going to setup a ZTP environment to be able to run the basic configuration on a new Juniper switch. Once the basic configuration is done, we will run homer to deploy the switch configuration. If you want to know more about homer please check: https://wikitech.wikimedia.org/wiki/Homer

Prerequisites

For this tutorial I will be using :

- EVE-NG 2.0.3-112

- VQFX model: vqfx-10000 running JUNOS 19.4R1.10

- DHPC/TFTP VM (IP:10.192.16.5/install1001.dfw.labnet)

- Homer VM(IP:10.192.32.17/homer1001.dfw.labnet)

- Netbox VM(IP:10.192.32.3/netbox1001.dfw.labnet)

- DNS server(IP:10.192.16.2/ns0.dfw.labnet)

All the VM's are running on Proxmox 7.3.4

Setup and Configuration

The section is the just the section needed to make ztp work.

Note: We will generate the juniper_ztp file using later on a python script

        include "/etc/dhcp/juniper_ztp";   
}
