1.1.2 Introduction to MP

Multilink PPP (MP) provides an approach to increasing bandwidth. It allows multiple
PPP links to form an MP bundle. After receiving a packet, MP segments (in case the
packet is large) and distributes it over multiple PPP links in a bundle on a segment by
segment basis. The receiving MP then assembles these segments and passes the
resulted packet to the network layer.
MP functions to:
Increase bandwidth, or dynamically increase/reduce bandwidth in combination
with DCC
Load sharing
Backup
Decrease transmission delay due to the use of fragmentation
MP can work on any physical or virtual interfaces with PPP encapsulation, such as
serial, ISDN BRI/PRI, and PPPoX (PPPoE, PPPoA, or PPPoFR). However, a multilink
bundle is preferred to include only one type of interface.

1.2 Configuring PPP

Fundamental PPP configuration tasks include:
Configure the data link protocol encapsulated on the interface to be PPP
Configure the polling interval
Configure PPP authentication mode, user name and user password
Advanced PPP configuration tasks include:
Configure PPP negotiation parameters
Configure PPP link quality control (LQC)
The fundamental configuration is the parameter setting that must be performed for
running PPP on the router, whereas the advanced configurations are the options that
can be configured as needed.
