MPLS Multilink PPP Support

Note This chapter is not applicable on the ASR 900 RSP3 Module for the Cisco IOS XE Release 3.16.
The MPLS Multilink PPP Support feature ensures that MPLS Layer 3 Virtual Private Networks (VPNs)
with quality of service (QoS) can be enabled for bundled links. This feature supports Multiprotocol Label
Switching (MPLS) over Multilink PPP (MLP) links in the edge (provider edge [PE]-to-customer edge [CE])
or in the MPLS core (PE-to-PE and PE-to-provider [P] device).
Service providers that use relatively low-speed links can use MLP to spread traffic across them in their MPLS
networks. Link fragmentation and interleaving (LFI) should be deployed in the CE-to-PE link for efficiency,
where traffic uses a lower link bandwidth (less than 768 kbps). The MPLS Multilink PPP Support feature
can reduce the number of Interior Gateway Protocol (IGP) adjacencies and facilitate load sharing of traffic.
