How-To: Bond Multiple DSL connections with MLPPP and a MikroTik RouterBoard

Multi Link Point to Point Protocol is a nifty protocol which allows for the bonding of multiple lines.  With a MLPPP enabled DSL account, two or more lines, DSL modems in bridged mode and a bonding router such as a Mikrotik routerboard, you can effectively quadruple the speed (minus a little overhead) of a DSL connection.
Here's how! connect to the Mikrotik via the Winbox application and follow along.
PPP -> "Interface" Tab:
        - Hit the red plus sign
        - pick "PPPoE Client"
