Our service provider is giving ADSL connection on Ethernet(RJ45(HWIC-1FE))interface on router side.Is the configuration on the router is same like ADSL ports(RJ11-ATM0/1/0)?.Please advise?
the configuration can be similar if using PPPoE:
the ethernet interface is configured to use the pppoe client feature that can use a dialer interface.
newer IOS images don't need to use the vpdn to be able to perform PPPoE client.
see for example for 12.4
Hope to help
