How To Configure DHCP On Juniper (New ELS Config)

In this video we’ll show you how to configure DHCP on Juniper devices running ELS. DHCP stands for Dynamic Host Configuration Protocol, and is responsible for assigning IP addresses to PCs on the network that has their network settings set to automatically acquire an IP address.

You will find that most newer devices run ELS software, but for those of you who want to know how to configure DHCP on SRX firewalls as well as old switches (non-ELS), here is an example config:

set system services dhcp pool 10.10.0.0/24 address-range low 10.10.0.10
set system services dhcp pool 10.10.0.0/24 address-range high 10.10.0.254
set system services dhcp pool 10.10.0.0/24 name-server 192.168.1.24
set system services dhcp pool 10.10.0.0/24 name-server 10.10.200.16
set system services dhcp pool 10.10.0.0/24 router 10.10.0.1

set interfaces vlan unit 11 family inet address 10.10.0.1/24

set vlans VLAN11 description “End User LAN Network”
set vlans VLAN11 vlan-id 11
set vlans VLAN11 l3-interface vlan.11

We use EVE-NG for all our lab simulations, and in this lab we used a virtual QFX connected to three Windows Server machines, all set to automatically acquire an IP address. .
