Cisco CCNA- DHCP Server
- 1. CISCO CCNA DHCP SERVER To watch our Cisco CCNA Video Trainings Please Check out the link below: www.asmed.com/c1 ASM Educational Center Inc. (ASM) Where Training, Technology & Service Converge Phone: (301) 984-7400
- 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.
