I prepare for ISCW exam, i have some confuse about PPPoE concepts:
- The final before CPE router send PPPoE frame to aggregation router, it have to encapsulate PPPoE frame to ATM ?
- The configuration over the Ethernet Interface, I'm not see any ATM configuration, how CPE router encapsulate PPPoE into ATM frame ?
- Follow your link if the WAN interface is an Ethernet Interface, the DSL modem will encapsulate Ethernet frame to ATM Cell and send over local loop to CO ?
yes this can be done
- If the WAN Interface is an ATM interface, the DSL modem or other ISP devices is not need ?
Hope to help
