RouterOS MLPPP
There is now Multilink PPP support in PPPoE client,
starting with v3.10.
PPPoE client “interface” property has been changed to
“interfaces”, and new property in status (monitor) has
been added - “active-links”.
Active-links shows how many links are active
(bundled together). To enable Multilink PPP, simply
specify multiple interfaces in “interfaces”
property, it will bundle them together, if PPPoE server
allows that.

one login name, one PPPoE session over multiple interfaces, one IP address, one pppoe interface in the router
