Configuring Remote Access to MPLS VPN
TheCisco 10000 series router supports the IP virtual private network (VPN) feature for Multiprotocol 
Label Switching (MPLS). MPLS-based VPNs allow service providers to deploy a scalable and 
cost-effective VPN service that provides a stable and secure path through the network. An enterprise or 
Internet service provider (ISP) can connect to geographically dispersed sites through the service 
provider’s network. Using the MPLS backbone, a set of sites are interconnected to create an MPLS VPN.
The remote access (RA) to MPLS VPN feature on the Cisco 10000 series router allows the service 
provider to offer a scalable end-to-end VPN service to remote users. The RA to MPLS VPN feature 
integrates the MPLS-enabled backbone with broadband access capabilities. By integrating access VPNs 
with MPLS VPNs, a service provider can:
  • Enable remote users and offices to seamlessly access their corporate networks
  • Offer equal access to a set of different ISPs or retail service providers
  • Integrate their broadband access networks with the MPLS-enabled backbone
  • Provide an end-to-end VPN service to enterprise customers with remote access users and offices
  • Separate network access and connectivity functions from ISP functions
