@erindesu I think the point of PPPoE is so the ISP can tell which packets belong to which subscriber when the medium is shared (PON, fiber-to-the-node, DSL, etc). Although my current ISP is somehow providing me with fiber service that uses plain old DHCP and Ethernet. Which I love and cherish very much. But I'm sure it'll be PPPoE o'clock again if I ever move or if the ONT ever needs replacement.

@argv_minus_one@mastodon.sdf.org if you want to learn more about it, I really recommend this DENOG conference about PPPoE vs IPoE for ISPs :neocat_science: https://youtu.be/36TgDD-g-3k @erindesu@tech.lgbt

@argv_minus_one the funny part is that our current ISP (it's not their choice to use PPPoE, from what i heard of them they don't like it either) the username and password are uvt. At least PON has it's own mechanisms to identify subscriber.

@argv_minus_one @erindesu 1500 MTU within PPPoE is standardized and possible, just needs turning on.

@argv_minus_one @erindesu My fiber connection is just Ethernet, and so were my VDSL connection (back in 2007) and cable before that. Never had to suffer PPPoE at home.
