Configuring MPLS VPN Mapping
This chapter describes the Cisco Multiprotocol Label Switching (MPLS) Virtual Private Network (VPN)
Mapping of Routed Sessions implementation on all Cisco digital subscriber line access
multiplexers (DSLAMs) using the second-generation network interface module (NI-2).
MPLS VPN Overview
The Cisco MPLS VPN mapping of routed sessions implementation enables Cisco DSLAMs with NI-2
controller cards and connected customer premises equipment (CPE) to participate in MPLS VPNs. This
implementation promotes the rapid deployment of secure IP VPNs that enable revenue-generating
services, such as:
Intranets
Extranets
Application and data hosting
Network commerce
Secure telecommuter access to corporate networks
Figure 6-1 shows an example of an MPLS VPN with a service provider (P) backbone network, service
provider edge routers (PEs), and customer edge routers (CEs).
