Multiclass MLPPP enables the fragmentation of data packets of different priorities into
multiple classes in an MLPPP bundle. It enables you to interleave data packets of higher
priority between packets of lower priority before transmission.
When the MLPPP bundle consists of more than one multilink interface, multiclass MLPPP
ensures the delivery of high-priority, delay-sensitive traffic, such as voice and video, in
the proper sequence. Multiclass MLPPP accomplishes this by creating separate transmit
and receive contexts for every multilink class in the MLPPP bundle. The transmit and
receive contexts contain the sequence numbers and all other statistics pertaining to the
multilink class
You can configure fragmentation and reassembly on a multiclass MLPPP interface.
Fragmentation is the process by which a large packet is broken up into multiple smaller
fragments for simultaneous transmission across multiple links of an MLPPP bundle.
Reassembly is the process by which the destination router reassembles the fragments
into the original packets.
