MPLS Multilink PPP Support and PE-to-CE Links
The figure below shows a typical Multiprotocol Label Switching (MPLS) network in which the provider edge
(PE) device is responsible for label imposition (at ingress) and disposition (at egress) of the MPLS traffic.
In this topology, Multilink PPP (MLP) is deployed on the PE-to-customer edge (CE) links. The Virtual Private
Network (VPN) routing and forwarding instance (VRF) interface is in a multilink bundle. There is no MPLS
interaction with MLP; all packets coming into the MLP bundle are IP packets.

The PE-to-CE routing protocols that are supported for the MPLS Multilink PPP Support feature are external
Border Gateway Protocol (eBGP), Open Shortest Path First (OSPF), and Enhanced Interior Gateway Routing
Protocol (EIGRP). Static routes are also supported between the CE and PE devices.
Quality of service (QoS) features that are supported for the MPLS Multilink PPP Support feature on CE-to-PE
links are link fragmentation and interleaving (LFI), compressed Real-Time Transport Protocol (cRTP), policing,
marking, and classification.
