Cisco Systems 1000 Series Manual De Usuario

Multilink Point-to-Point Protocol (MLP) provides support to aggregate the bandwidth of low-speed 
WAN and broadband links into a single entity, referred to as a bundle interface. A bundle interface is a 
logical entity that provides a single point in which other features (for example, Quality of Service [QoS]) 
can be attached. MLP provides incremental bandwidth on demand, by adding additional links to the 
bundle, as needed. MLP also enables interleaving of latency-sensitive priority traffic with fragmented 
nonpriority traffic using link fragmentation and interleaving (LFI).

Member links that are a part of an MLP bundle can be bundled across ports on:

The same shared port adapter (SPA)

Different SPAs on the same SPA interface processor (SIP)

Different SPAs on different SIPs

The Cisco IOS XE software supports MLP links for serial (T1, E1, NxDS0) and broadband topologies 
such as Multilink PPP over ATM (MLPoA), Multilink PPP over Ethernet (MLPoE), Multilink PPP over 
Ethernet over ATM (MLPoEoA), and Multilink PPP over LNS (MLPoLNS). Additionally, the Cisco IOS 
XE software allows the device to operate as an L2TP Access Concentrator (LAC), L2TP Network Server 
(LNS), or PPP Termination and Aggregation (PTA) device.

This document describes the features, limitations, and scaling of MLP on the Cisco ASR 1000 Series 
Aggregation Services Routers running the Cisco IOS XE software. For information about the 
configuration and operation of MLP in the Cisco IOS XE software, see the “Configuring Multilink PPP 
Connections” chapter in the
