2. Cisco CCNA-DHCP Server 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.

3. Cisco CCNA-DHCP Server 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 .

4. Cisco CCNA-DHCP Server R1#show ip int brief                                                                                                                      Hint : Always start with ip DHCP? 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

5. Cisco CCNA-DHCP Server 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

6. Cisco CCNA-DHCP Server 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

7. Cisco CCNA-DHCP Server 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

8. Cisco CCNA-DHCP Server Here is my show run ip dhcp pool lan100 network 10.10.10.0 255.255.255.0 default-router 10.10.10.100

9. Cisco CCNA-DHCP Server Step 2) Lets exclude some address R1#config t Enter configuration commands, one per line.  End with CNTL/Z. R1( config )# ip dhcp ? excluded-address  Prevent DHCP from assigning certain addresses pool              Configure DHCP address pools R1( config )# ip dhcp exc R1( config )# ip dhcp excluded-address ?

10. Cisco CCNA-DHCP Server A.B.C.D  Low IP address R1( config )# ip dhcp excluded-address 10.10.10.1 ? A.B.C.D  High IP address < cr > R1( config )# ip dhcp excluded-address 10.10.10.1 10.10.10.20 ? < cr > R1( config )# ip dhcp excluded-address 10.10.10.1 10.10.10.20

11. Cisco CCNA-DHCP Server Lets see your show run ip dhcp excluded-address 10.10.10.1 10.10.10.20 ! ip dhcp pool lan100 network 10.10.10.0 255.255.255.0 default-router 10.10.10.100 !

12. Cisco CCNA-DHCP Server Now I will create a another scope for LAN 20.20.20.0/2 R1#config t Enter configuration commands, one per line.  End with CNTL/Z. R1( config )# ip dhcp ? excluded-address  Prevent DHCP from assigning certain addresses pool              Configure DHCP address pools R1( config )# ip dhcp pool R1( config )# ip dhcp pool ? WORD  Pool name R1( config )# ip dhcp pool lan200

13. Cisco CCNA-DHCP Server 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

14. Cisco CCNA-DHCP Server R1( dhcp-config )# netw R1( dhcp-config )#network 20.20.20.0 ? A.B.C.D  Network mask R1( dhcp-config )#network 20.20.20.0 255.255.255.0 R1( dhcp-config )#de R1( dhcp-config )#default-router 20.20.20.100 R1( dhcp-config )#

15. Cisco CCNA-DHCP Server Here is my show run ip dhcp excluded-address 10.10.10.1 10.10.10.20 ! ip dhcp pool lan100 network 10.10.10.0 255.255.255.0 default-router 10.10.10.100 ip dhcp pool lan200 network 20.20.20.0 255.255.255.0 default-router 20.20.20.100

16. Cisco CCNA-DHCP Server Now I will give out 2nd exclusion R1#config t Enter configuration commands, one per line.  End with CNTL/Z. R1( config )# ip dhcp ? excluded-address  Prevent DHCP from assigning certain addresses pool              Configure DHCP address pools

17. Cisco CCNA-DHCP Server R1( config )# ip dhcp excluded-address ? A.B.C.D  Low IP address R1( config )# ip dhcp excluded-address 20.20.20.1 20.20.20.20 ? < cr > R1( config )# ip dhcp excluded-address 20.20.20.1 20.20.20.20

18. Cisco CCNA-DHCP Server Here is my show run ip dhcp excluded-address 10.10.10.1 10.10.10.20 ip dhcp excluded-address 20.20.20.1 20.20.20.20 ! ip dhcp pool lan100 network 10.10.10.0 255.255.255.0 default-router 10.10.10.100

19. Cisco CCNA-DHCP Server ip dhcp pool lan200 network 20.20.20.0 255.255.255.0 default-router 20.20.20.100 ! interface FastEthernet0/0 ip address 10.10.10.100 255.255.255.0 duplex auto speed auto !

20. Cisco CCNA-DHCP Server interface FastEthernet0/1 ip address 20.20.20.100 255.255.255.0 duplex auto speed auto *** Now If  I go to my pc I will say obtain IP address; and you will see IP address is given to each PC on left side and right side and we should be able to ping from left to right.
