Chapter 1 About Cisco IP Solution Center
Overview of ISC
It is not required that the set of IPv4 addresses used in any two VPNs be mutually exclusive because the
PEs translate IPv4 addresses into IPv4 VPN entities by using MP-BGP with extended community
attributes.
PEs translate IPv4 addresses into IPv4 VPN entities by using MP-BGP with extended community
attributes.
The set of IP addresses used in a VPN, however, must be exclusive of the set of addresses used in the
provider network. Every CE must be able to address the PEs to which it is directly attached. Thus, the
IP addresses of the PEs must not be duplicated in any VPN.

ISC Features
ISC offers the following features:
•
High Availability and Distributed Architecture
•
Various protocols supported for the PE-CE link
•
Multicast VPN support
•
VRF Lite/Multi-VRF support
•
Site of Origin support
•
ATM/IMA interface support
•
Unmanaged CPE with no CPE definition required
•
Single service request for multiple MPLS VPN links
•
MPLS VPN Service Policy support
•
Service workflow for customizing MPLS VPN service activation
•
Layer 2 Ethernet Access into MPLS VPNs
One of ISC key features is to hide much of the complexity in dealing with the deployment of Metro
services.
services.
•
Autodiscovery: ISC supports Autodiscovery of network elements, of network topology, and MPLS
VPN services. This feature greatly reduces the initial effort needed to insert ISC in the service
provider’s operation. For details, refer to

Managed CLE: ISC offers the capability of managing the Customer Located Equipment (CLE),
which gives the service provider the possibility of offering a managed Metro Service to their
customer (configuration, monitoring, and auditing of the managed CLE).

Plug and Play: As the network and customer base grow, network elements can be added to the
network. ISC, working in collaboration with CNS Intelligent Agents, is able to detect newly added

This gives the service provider the ability to rapidly deploy services and network elements.
•
End-To-End Service Management: ISC manages the entire end-to-end provisioning of MPLS
VPN services. Assuming that the network operator defined MPLS VPN service policy and the
parameters that are to be editable by the service operator during the provisioning process, ISC
translates these service requirements into IOS configurations. ISC does a just-in-time Cisco IOS
configuration download, which consist of always validating the configuration of the real devices
before applying the needed configuration.

Once a service is configured, ISC makes sure that the service configuration is the intended one by
checking the configuration and verifying that VPN routing is operational.
