Rahul is perfectly correct. In the SP world, regulatory concerns may enter. For example, in the US, an ILEC can't terminate IP as part of its basic service. It can use IP in its infrastructure, as, for example, putting an L2TP proxy client in one of its POPs, extracting the PPP, and then sending the PPP to the ultimate server at the ISP. If the transport for that last leg happened to be FR, PPPoFR might be an alternative, although I tend to prefer L2TP. > > > > > > >""Rahul Kachalia"" wrote in message >[EMAIL PROTECTED]">news:[EMAIL PROTECTED]... >> John, >> >> PPPoFR solution is to maintain leased line PPP end to end over SP's FR >> backbone..Following is the sample topology : >> >> CPE--PPP/LL--SP--FR+PPP--SP--PPP/LL--CPE >> >> But later started using in Broadband environment with following >topology >> : >> >> CPE--PPPoFR/xDSL--DSLAM--PPPoFR--SP--PPPoFR--ISP/Wholesale provider >> >> But now you will find PPPoE, oEoA, oA & oEoVLAN, as you can see >several >> L2 tech. is used but the goal is to maintain PPP end-to-end due to its >> feature for AAA purpose.. >> >> thanks, >> rahul. >> >> >> ""John Neiberger"" wrote in message >> [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... >> > I believe someone might have mentioned this recently but since >> > I'm studying it right now I thought I'd ask again... >> > >> > What the heck would be a real-world application of PPP over >> > Frame Relay?
