From what I have understood till now about PPPoE protocol.
My question:
When I have two host devices connected to my CPE, will both of my devices use the existing PPPoE session (already established when I setup my CPE) for internet access ? Or will both the devices have two different PPPoE sessions ?
The CPE would establish the PPPoE session with the provider and terminate the WAN connectivity. Hosts would sit on the LAN and have no knowledge of PPPoE. The hosts send any Internet bound traffic to their default gateway (the CPE) and the CPE routes the traffic onwards through the PPPoE session. So, both hosts use the same PPPoE session, but indirectly, they don't have any awareness that the session exists, but their Internet bound traffic will pass over the session. So to answer your question, there is only one PPPoE session, the hosts do not establish their own, they do not know it exists, all their traffic (Internet bound) passes over the same PPPoE session.
