As an aside, I recently had a top 5 firewall vendor tell one of me and
one of my co-workers that all DSL is PPPoE, including but not limited to
HDSL, SDSL, ADSL, etc. Considering that my employer is an ISP offering
DSL, and using PPPoA and not PPPoE, I had quite a laugh at his expense.
From what I understood, PPPoA allows one to use use a larger MTU (4352)
all the way to the CPE device, instead of 1500 to the CPE device and
1492 for any devices behind said CPE device. There are more reasons that
seem to elude me at the moment - can anyone else expound on this?
