Juniper DHCP Server Configuration

We already configure our QEMU in GNS3 and run our vSRX Router. Now its time to configure DHCP server in our vSRX router. Lets began.
Logical Diagram for this tutorial



To configure DHCP server

Assign Lowest and highest IP range
root# set system services dhcp pool 192.168.1.0/24 address-range low 192.168.1.50 high 192.168.1.200

Assign DNS server (in my case I had used Router interface IP)
root# set system services dhcp pool 192.168.1.0/24 name-server 192.168.1.1

Assign IP address of the router
root# set system services dhcp pool 192.168.1.0/24 router 192.168.1.1

Assign the lease time
root# set system services dhcp pool 192.168.1.0/24 default-lease-time 3600



Assign DHCP as an allowed inbound service for the interface which we are going to enable DHCP.

root# set security zones security-zone untrust interfaces ge-0/0/1 host-inbound-traffic system-services dhcp

Assign IP address to the client faced interface.
root# set interfaces ge-0/0/1 unit 0 family inet address 192.168.1.1/24



Check our client get the IP Address from the server.


How to statically assign IP with fixed MAC address

root#set system service dhcp static-binding 00:50:79:66:68:00 fixed-address 192.168.1.100

PC1>show ip

Request DHCP IP

PC1>dhcp -d




Enjoy
