Configuring Multilink PPP Bundles
Multilink bundles can have from 1 to 8 members (ports) specified. The bundles aggregate
channelized ports which define available bandwidth to carry data over a DS1 channel. 56
multilink bundles can be configured per MDA. 256 MLPPP groups are supported per ASAP
MDA. Each bundle represents a single connection between two routers.
Multilink bundling is based on a link control protocol (LCP) option negotiation that permits a
system to indicate to its peer that it is capable of combining multiple physical links into a bundle.
Multilink bundling operations are modeled after a virtual PPP link-layer entity where packets
received over different physical link-layer entities are identified as belonging to a separate PPP
network protocol (the Multilink Protocol, or MP) and recombined and sequenced according to
information present in a multilink fragmentation header. All packets received over links identified
as belonging to the multilink arrangement are presented to the same network-layer protocol
processing machine, whether they have multilink headers or not.
When you configure multilink bundles, consider the following guidelines:
• Multilink bundle configuration should include at least two ports.
• A maximum of 8 ports can be included in a multilink bundle.
• Multilink bundles can only be aggregated on a single MDA.
