A typical MLPPP configuration has at least two components:

A bundle interface

An interface running PPP that is made multilink-enabled and attached to the

bundle interface.

To establish communication over a PPP Multilink, a MRRU (Maximum Receive

Reconstructed Unit) configuration option is sent to the peer during LCP

negotiation. Optionally, an Endpoint Discriminator Option or SSHNF Option may

also be sent out. LCP negotiation and optional link authentication take place on

each bundle link. IPCP negotiation happens over the bundle, meaning IPCP

packets may be sent on any one of the bundle links. Certain LCP packets like LCP

Echo-Request and LCP Echo-Reply may be transmitted over the bundle. IP

packets are sent over the bundle.

The MLPPP packet is encapsulated using an MLPPP header which is different

from the standard PPP header. It contains a sequence number and additionally

allows for fragmentation or re-assembly of the packet.

MLPPP is also referred to as MP or MPPP.
