*) pppoe - use default MTU of 1492;
Wow! Maybe one of my ISPs using MikroTik will finally offer 1492 instead of the current default 1480. And maybe rfc4638 in the current lifetime. (In the next decade when/if they move to v7, but I have a feeling they’ve been bought already and the new company will start using other equipment till then).
Does this mean that PPPoE “auto” MTU is no longer tied to the underlying ethernet interface MTU -20 Bytes of MikroTik “headers”? as described in http://forum.mikrotik.com/t/netflix-and-ipv6/145906/1 and support ticket SUP-38224 ?
