DHCP Option 66 - Cisco Routers

[mazhar]

Can anyone help me in configuring the DHCP option 66 to auto provision url during dhcp lease on CISCO ROUTERS.

Assuming you already have the dhcp pool setup.

For the sake of example, we'll say it's called "DHCPPOOL"

ip dhcp pool DHCPPOOL
option 66 ascii "http://whatever.you.want.here/"

If you have trouble with the device not picking up the option 66, it could be because of the quotes. Try removing them like:

ip dhcp pool DHCPPOOL
no option 66 ascii "http://whatever.you.want.here/"
option 66 ascii http://whatever.you.want.here/

Hi,

Thank you for the post. I tried the option 66 as specified in your post. It doesn't work. I checked it on Cisco 1841, Cisco 837 routers. May be it takes only the IP address for the TFTP server and it doesn't work for a URL.
