Hmm, alpha is using PPPoA (to an onboard solos card). I thought PPPoA had a higher MTU than PPPoE... was that just my imagination?
Correct, PPPoA supports an MTU of 1500, but PPPoE has 8 more bytes of overhead, reducing this to 1492.
There are lots of placebo anecdotes to argue the merits of either one.
So why does my transcript (upthread) indicate that alpha is PMTUDing it down to 1492?
