Lab Title: Configure Cisco 2600 Router as a DHCP Server

 

Purpose:

1.       Understand how to configure Cisco 2600 as a DHCP server.

2.       Understand how the DHCP server distribute IP

 

Preparation:

1.       DHCP, ARP, DNS.

 

Topological:

 

Requires:

1.       Don’t distribute IP address 172.20.30.1 and from 172.20.30.200 to 172.20.30.254

2.       Default gateway is 172.20.30.254.

3.       Dns server is 208.67.222.222

4.       The ranger of IP that can be distributed is 172.20.0.0/16

 

Procedure:

1. Open a terminal to setup the router:

Router>en

Router#conf t

Router(config)#ip dhcp excluded-address 172.20.30.1

Router(config)#ip dhcp excluded-address 172.20.30.200 172.20.30.254

Router(config)#ip dhcp pool testdhcp

Router(dhcp-config)#?

  default-router  Default routers

  dns-server      Set name server

  exit            Exit from DHCP pool configuration mode

  network         Network number and mask

  no              Negate a command or set its defaults

Router(dhcp-config)#default-router 172.20.30.254

Router(dhcp-config)#dns-server 208.67.222.222

Router(dhcp-config)#network 172.20.30.0 255.255.0.0

Router(dhcp-config)#end

 

Router#conf t

Router(config)#interface fastEthernet 0/0

Router(config-if)#ip address 172.20.30.1 255.255.0.0

Router(config-if)#no shut

Router(config-if)#end

 

2.       Check the PC’s IP address. Open a command line window,

> ipconfig /renew

              --- Renew the IP address.

> ipconfig /all

              --- Show current IP setting.

 

 

3.       Back to the terminal of router:

Router#show arp          

---Display Arp table

Router#show ip dhcp binding

       --- Display all the distributed IP
