In this lab we are trying to make our Cisco Router Act as a DHCP server , that is R1 will give ip address 10.10.10.0/24 to left side Pc and it will give the IP address 20.20.20.0/24 to right side of PC. The Goal is Prepare you for your Cisco CCNA Certification exam.

DHCP goes thru these steps:
DORA

Step 1)   D= Discover packet

Step 2)   O= offer packet

Step 3)   R=Request packet

Step 4)   A=Acknowledge packe

Hint: When you configure the DHCP; your LAN must match with the ip address of your int f0/0  and Int f0/1.

R1#show ip int brief

Interface IP-Address OK?  Method  Status Protocol
FastEthernet0/0 10.10.10.100  YES manual  up up
FastEthernet0/1 20.20.20.100 YES manual  up up
Vlan1 unassigned YES unset administratively down down

 

Hint: Always start with ip DHCP?

Now I will go create a scope:

Step 1) define your Pool of address
R1#
R1#config t
R1(config)#ip dhcp ?
excluded-address  Prevent DHCP from assigning certain addresses
pool              Configure DHCP address pools

R1(config)#ip dhcp POOL ?

WORD  Pool name
R1(config)#ip dhcp POOL lan100
R1(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
option          Raw DHCP options
R1(dhcp-config)#NETWork ?
A.B.C.D  Network number in dotted-decimal notation
R1(dhcp-config)#NETWork 10.10.10.0 ?
A.B.C.D  Network mask

R1(dhcp-config)#NETWork 10.10.10.0 255.255.255.0
R1(dhcp-config)#default-router ?

A.B.C.D  Router’s IP address
R1(dhcp-config)#default-router 10.10.10.100
