If you are using the subinterface then its a better idea to configure it on the sub-interface.

Thanks Waris, I have already done so but i needed confirmation as I also had channelized STM1 circuits. I am also wondering with ADSL, I have several point-point interface for ADSL specifying a PVC bounding all PPP to a Virtual Template, is it necessary to place the "ip cef accounting non-recursive external" on the virtual template or just leave it on the main ADSL ATM point-point interface on the PE.
