Increasing Enterprise Deployment of MPLS


As we have seen in Chapter 5, "Layer 3 VPNs," MPLS VPNs can also be deployed by enterprises for network segmentation or VLAN/VPN requirements. 802.1X authentication, which is widely used in the enterprise, can be mapped to trusted VLANs, and these VLANs in turn can be mapped to VRFs and VPNs for campus-wide and network-wide segmentation of users within the enterprise. Many financial houses and airport authorities are deploying MPLS VPNs in their networks to provide VPN services to their respective departments. In the future such deployments will increase the need to more ubiquitously connect MPLS networks together with provider networks or connect MPLS privately using the Inter-AS connectivity model. Such demands might lead to MPLS interconnect or exchange, or even clearing houses whose business model will be to seamlessly connect MPLS networks together.
