[Scottish] PPPoE vs PPPoA

[Matt Causey]

In my understanding, PPPoE is the newer, more flexible protocol...as it
allows more detailed AAA through the ISPs RADIUS infrastructure.  But there
are no benefits to the end ISP user AFAIK.

The other options there, as you'll find, define the topology of your
connection (do you want the DSL modem to also function as a router with a
management address, or do you want the modem to simply act as a bridge so
that you can perform the PPPx authentication at another device, etc.).
