Deploying and offering MPLS VPN services for enterprise customers requires planning of network resources, deploying, maintaining and finally configuring the network elements and services. This manual procedure can be time consuming and not accurate. A service provider needs to automate all these steps in order to be stay competitive in this
Figure 1-1 shows all the major elements and devices that a service provider can employ to fully deploy ISC MPLS VPN management services.
A customer edge router (CE) is connected to a provider edge router (PE) in such a way that the customer’s traffic is encapsulated and transparently sent to other CEs, thus creating a virtual private network. CEs advertise routes to the VPN for all the devices in their site. The ISC provisioning engine accesses the configuration files on both the CE and PE to compute the necessary changes to those files that are required to support the service on the PE-CE link.
