What is the difference between PPPoE and PPPoA?
Posted on 2006-07-08
The other day, I had to get a new DSL modem from Bellsouth. Before I could use it, I had to configure it for a wireless router connection. During the configuration process, I had to set the change PPPoE to Bridge Mode in order to disable DHCP within the DSL Modem, thereby, leaving the DHCP things handled by the router. It is my understanding from a previous post that two network devices, like a DSL modem and router should not have DHCP enabled because of possible conflicts. Withing the router, I left it at PPPoE as the internet connection type.
Following the configuration of the DSL Modem and router, I was able to get online just fine through the router. While within the configuration, I dd see some things which was somewhat confusing to me. For instance, I saw an option called PPPoA as an internet connection type. How is PPPoA different from PPPoE? I believe PPPoE means point-to-point over ethernet, but, I do not know what PPPoA is all about. Additionally, I believe PPPoE is used whenever there is a direction connection between two devices using an ethernet cable as well.
In any case, I appreciated any additional feedback and/or corrections on any assumptions I may have here.
Thanks in advance for any attention given to this post.
