DHCP Pool on Cisco 1721

[secureinc]

I need to use my router as a DHCP server. I need the following ip scheme used...

IP address pool - 192.168.1.3 - 192.168.1.50
Default Gateway - 192.168.1.1
DNS - 192.168.x.x

Thank you for any help you may have!!!!

I just set up my cisco 2611 router with internal IP addresses similar to what you are doing but I used the win 2000 server to distribute the DHCP addresses. I had posted here and that is what several people told me was the best way and I can say after doing it, it is nice to have the win 2000 interface to troubleshoot DHCP instead of having to type everything in manually!

Either way, you can use Cisco Config Maker on a PC that is WYSIWYG and then upload it to the router. This takes alot of the hassle out of it and there is a place that helps you to set up your router as a DHCP server.

Cisco config maker (make sure your router is listed!)

Using IP Helper addresses, one router serves the entire network. IP-Directed broadcasts will assist in the decision to know which scope to provide the client.


On the router that serves internal addresses, here are two of many possible scopes

ip dhcp pool DOT96
network 192.168.1.96 255.255.255.240
dns-server 68.10.16.25 68.10.16.30
default-router 192.168.1.97
lease 7 23 59

ip dhcp pool DOT64
network 192.168.1.64 255.255.255.192
default-router 192.168.1.34
dns-server 68.10.16.25 68.10.16.30 68.10.9.30
lease 7 23 59

Then "reservations" are made with the exclude command

ip dhcp excluded-address 192.168.1.97
ip dhcp excluded-address 192.168.1.98
ip dhcp excluded-address 192.168.1.65
ip dhcp excluded-address 192.168.1.66
ip dhcp excluded-address 192.168.1.67


Enjoy.
