Multilink PPP (MLP) over multiple interfaces
If you have two or more communications links between the router and the destination, you can use multilink PPP to send traffic over several interfaces in parallel to get higher throughput. Asynchronous serial interfaces, ISDN BRI interfaces, and ISDN PRI interfaces can make use of multilink PPP. Multilink PPP works best on digital lines such as ISDN; it is less effective on low-speed analog connections.
