MPLS L3VPN overview
MPLS L3VPN is a L3VPN technology used to interconnect geographically dispersed VPN sites. MPLS
L3VPN uses BGP to advertise VPN routes and uses MPLS to forward VPN packets over a service provider
backbone.
MPLS L3VPN provides flexible networking modes, excellent scalability, and convenient support for MPLS
QoS and MPLS TE.
Basic MPLS L3VPN architecture
Figure 107 Basic MPLS L3VPN architecture
A basic MPLS L3VPN architecture has the following types of devices:
•
Customer edge device—A CE device resides on a customer network and has one or more interfaces
directly connected to a service provider network. It does not support VPN or MPLS.
•
Provider edge device—A PE device resides at the edge of a service provider network and connects
to one or more CEs. All MPLS VPN services are processed on PEs.
•
Provider device—A P device is a core device on a service provider network. It is not directly
connected to any CE. A P device has only basic MPLS forwarding capability and does not handle
VPN routing information.
