Multilink PPP Fragments
Multilink fragments are called
packets
(per RFC 1990, section 3, page 7, which states “individual
fragments, which are the 'packets' in the Multilink Protocol.”).
This feature negotiates the Maximum
Received Reconstructed Unit (MRRU) option during the PPP LCP
negotiation to indicate to its peer that it can combine multiple
physical links into a bundle.
Prior to the adoption of RFC 1990,
there was no standardized way to use both of the B channels and
ensure proper sequencing.
MLP is interoperable between Cisco
routers running Cisco IOS software and Cisco 700 series routers, and
with most routers that conform to RFC 1990.
Use MLP with applications
in which bandwidth requirements are dynamic, such as remote LAN
access applications for telecommuters or small office, home office (SOHO)
environments.
