Configuring MLPPP Fragmentation and Reassembly

You can configure MLPPP fragmentation and reassembly on a static link interface
before adding the link to a bundle, or in a profile assigned to a dynamic MLPPP
interface. You can also configure fragmentation and reassembly for all current
member links in an MLPPP bundle.

Overview

E Series routers support fragmentation and reassembly as part of their MLPPP
implementation. 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.

Configuring MLPPP Fragmentation and Reassembly
Specify an IP loopback interface with which dynamic IP interfaces created using
this profile will be associated.
host1(config-profile)#ip unnumbered loopback 0
(Optional) Set other desired PPP characteristics by using the ppp commands
described in "Configuring Authentication" on page 279 and "Configuring Other
PPP Attributes" on page 281.
Use in a profile to enable the creation of dynamic MLPPP interfaces.
Example
host1(config-profile)#ppp multilink enable
Use the no version to cause the LNS to reject any incoming requests to create
dynamic MLPPP interfaces.
See ppp multilink enable.
Use to create a profile.
Specify a profile name with up to 80 characters.
Example
host1(config)#profile dynmlppp1
Use the no version to remove a profile.
See profile.
