I'm wondering if is possible to configure a Cisco Router 881 from a file on a tftp instruct on a DHCP option. I know is possible to configure the wan port through DHCP by configuring "ip address dhcp" but what I search is there is a way to act as an Cable Modem CPE, dowload the configuration file from the DHCP and load it.
on the DHCP I've configure the following option as it will be for a CPE
filename "tftp://172.16.0.1/conf";
warning I'm not asking how to configure DHCP server on Cisco Router.
