Configuring IP Interface to accept DHCP assigned address from ISP with DSL

[michael.regan]

I have a Cisco 1720 router with a WIC 1-Enet module that I need to configure so that it will accept a DHCP assigned IP address from my ISP using a DSL connection and PPOE. The ISP drops the connection every 24 hours (for security purposes) and requires the connection be reestablished in order to get a new IP address. Can you help by giving me a list of the configuration commands required?

Here is the url which has a sample config for "1700 with WIC-1ENET running PPPoE"..

To get dynamic ip address allocated by isp, you need to have "ip address negotiated" under the "interface dialer 1" which is linked with the "interface ethernet0"..That way 1700 will demand ip address from isp during ppp negotiaton phase (IPCP) which will be assigned to dialer interface linked to ethernet...Tejal
