About Cisco IP Solution Center
Cisco IP Solution Center (ISC) is a carrier-class network and service-management solution for the rapid
and cost-effective delivery of IP services. IP based services targeted to enterprise customers can
represent major revenue opportunities for service providers. Success in this highly competitive market
requires the ability to effectively plan, provision, operate, and bill for such IP services.
and cost-effective delivery of IP services. IP based services targeted to enterprise customers can
represent major revenue opportunities for service providers. Success in this highly competitive market
requires the ability to effectively plan, provision, operate, and bill for such IP services.
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 high-touch market.

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.
