This post is about configuring a CISCO router to act as a DHCP server in your network.
Task1: Configure R1 to act as a DHCP server and provide all network information to hosts in the LAN dynamically. (R1 and R2 are directly connected via Ethernet)
Server Configuration (R1)
!– enable dhcp server (default)
service dhcp ! — defining DHCP pool with all network information ip dhcp pool OFFICE !– defining static binding to R2 using its client-id ip dhcp pool STATIC !– exclude server and static addresses from the dynamic pool ip dhcp excluded-address 192.168.12.1 |
Client Configuration:
interface FastEthernet0/0 ip address dhcp client-id FastEthernet0/0 |
Troubleshooting and verfication:
IP address is assigned dynamically to R2
!– R2 f0/0 address is assigned via DHCP
R2(config-if)#do sh ip int b !– R1 bindings has R2 as a static entry R1#sh ip dhcp binding |
R2 gets its domain-name dynamically from R1
R2#sh ip domain networkers-online.com |
R2 sets R1 as a default gateway using a floating static route
R2#sh ip route Codes: C – connected, S – static, R – RIP, M – mobile, B – BGP D – EIGRP, EX – EIGRP external, O – OSPF, IA – OSPF inter area N1 – OSPF NSSA external type 1, N2 – OSPF NSSA external type 2 E1 – OSPF external type 1, E2 – OSPF external type 2 i – IS-IS, su – IS-IS summary, L1 – IS-IS level-1, L2 – IS-IS level-2 ia – IS-IS inter area, * – candidate default, U – per-user static route o – ODR, P – periodic downloaded static routeGateway of last resort is 192.168.12.1 to network 0.0.0.0 C 192.168.12.0/24 is directly connected, FastEthernet0/0 |
R2 learns Primary and secondary DNS servers from R1
R2#ping xyz.comTranslating “yahoo.com”…domain server (192.168.12.100) (192.168.12.101) % Unrecognized host or address, or protocol not running. |

I sincerely appreciate this tutorial , It help.
Thanks alot
One love
Nice article. I’ve been running the DAP-1522 for about 10 months now. It is hands down the most excellent hardware purchase I’ve made in a long time. I have it in bridge status to my NAS, HTPC and Xbox 360 to my home network. It works excellent with other D-Link device (My router is the DIR-655) and I will buy another DIR-655 for my home office.
thank you
