How to configure DHCP on Huawei Router

Dynamic Host Control Protocol (DHCP) is service which you can enable on any router or server. Basic idea is automate the process of assigning IP addresses to the end devices. On Huawei routers or L3 switch also you can configure this service. Huawei VRP let us configure in two forms one Global Pool and other is interface level. In this tutorial we do it with global pool. We gone use below topology to configure DHCP.

In  above topology AR1 Gig0/0/0 interface is already configured with IP address which going to act as gateway for the end device. So we can start directly with DHCP configuration:

STEP 1: Enable the DHCP in System View Mode

[AR1]dhcp enable

STEP 2: Configuring DHCP Pool Globally
[AR1]ip pool LAN-A
Info: It's successful to create an IP address pool.
[AR1-ip-pool-LAN-A]network 192.168.1.0 mask 24
[AR1-ip-pool-LAN-A]gateway-list 192.168.1.1
[AR1-ip-pool-LAN-A]dns-list 192.168.1.101 192.168.1.102

You can also verify your configuration use following command:

[AR1]display current-configuration 
#
ip pool LAN
 gateway-list 192.168.1.1 
 network 192.168.1.0 mask 255.255.255.0 
 dns-list 192.168.1.101 192.168.1.102 

#

STEP 3: Enabling DHCP On LAN facing Interface

[AR1]interface GigabitEthernet 0/0/0
[AR1-GigabitEthernet0/0/0]dhcp  select global 



In above  step we informed LAN facing interface about where to look for the pool once its receive DHCP request from clients.


Now you can you can go to your PCs command prompt and execute following command

ipconfig /release
ipconfig /renew

To check you PC has received IP

ipconfig



Finally, to confirm how many IP been released so for to the end devices you can use following command on the AR1.

In above diagram you can see what IPs been release so far.
