Bridged vs PPPoE Pass-through


I need to configure a Draytech Vigor 130 for a VDSL Swisscom connection in bridged mode

It is my router that will initiate and manage the PPPoE connection

Can anyone explain to me the difference between Bridged mode and PPPoE pass-through mode ?

I have done PPPoE on a Cisco router through the ISP DSL modem. It was the ISP who put the modem in Bridged Mode (so the Router could control the connection parameters). I think here that you would contact the ISP and have them put the modem in Bridged mode.

Thanks John
I know how to put a modem into bridged mode
I was just inquisitive about the nuance between bridged and 'PPPoE pass-through'
I believe the the latter is a kind of semi-bridged mode

Furthermore some modems in bridged mode are now longer accessible via layer three which seems logical to me; others however like Zyxel and Vigor can still be accessed through their IP address even though they are in bridged mode: weird

I have understood PPPoE pass though as enabling the router or firewall to make the connection. I use Bridged for this action. It think it is just a term some manufacturers use and amounts to the same thing (from a working perspective).

Well in fact this modem in particular offers both modes : Bridged and PPPoE Pass-Through hence my understanding that one is semi bridged while the other is fully bridged
