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
