How to Configure switch as DHCP Server

How to Configure switch as DHCP Server

Task

In this task, SW1 will be configured as a DHCP Server, and all four routers will be DHCP Clients. Configure DHCP Server functionality on SW11 using the following criteria:

Pool Name Network Address Subnet Mask Default Router Lease Time
vlan2 10.10.10.8 /29 10.10.10.9 1-day
vlan3 10.10.10.32 /29 10.10.10.33 1-day
vlan4 30.30.30.0 /26 30.30.30.1 1-day
vlan5 20.20.20.96 /27 20.20.20.97 1-day

Explanation

Configure all FastEthernet interfaces on the routers (connected to the switches shown in the topology diagram) to obtain their IP address dynamically via DHCP. Verify that your routers have obtained an appropriate DHCP IP address.

Verify that any one of your routers can ping the IP address of any other router.

verify router ping

Configuration

Step1 : Configure VTP mode Server , VTP domain CCNP and verify that all ports are trunk negotiated.

Configure VTP mode Server

Task 2 : Configure the L2 vlan for all Vlan on SW1.

SW1#conf t

Enter configuration commands, one per line. End with CNTL/Z.

SW1(config)#vlan 2

SW1(config-vlan)#vlan 3

SW1(config-vlan)#vlan 4

SW1(config-vlan)#vlan 5

SW1(config-vlan)#

Configure the L2 vlan

Task 3 :Verify that al ports connected to swith are 802.1Q trunk port . Configure the L3 vlan for all Vlan on SW1.

Verify ports connection

 

Verify ports connection 2

Task 6 : Configure the SW1 to make it as DHCP server .

SW1(config)#ip dhcp pool vlan2 SW1(dhcp-config)# network 10.10.10.8 255.255.255.248 SW1(dhcp-config)# default-router 10.10.10.9 SW1(dhcp-config)#!

SW1(dhcp-config)#  default-router 20.20.20.97

 

Task 7 : Configure the Routers so that it will take the ip address from DHCP server.

R1(config)#int range eth0/0-1

R1(config-if-range)#no shut

R1(config-if-range)#ip address dhcp

R2(config)#int range eth0/0-1
