Infrastructure Data
To provision an MPLS VPN service in ISC, you must first create an MPLS VPN Service Policy. In ISC, a Service Policy is a set of default configurations for creating and deploying a Service Request.
ISC supports two MPLS VPN Service Policy Types: Regular PE-CE and MVRFCE PE-CE. The following scenarios focus on the Regular PE-CE Policy Type.
The Regular PE-CE Policy Type is a normal PE to CE link between two devices. This Policy Type has two options:
•
CE Present enabled (One PE with one CE; two devices)
•
CE Present disabled (PE Only with no CE; one device)
Figure 7-1 shows an example of a normal PE to CE link between two devices.
Figure 7-1 PE to CE link with CE Present
In a PE to CE link with CE Present enabled, interfaces S3/1 and S1/0 are configured as an MPLS VPN link in the Service Request process.
Figure 7-2 shows an example of a PE Only link with no CE.
Figure 7-2 PE to CE link with No CE
In a PE to CE link with CE Present disabled, interface FE0/0 is configured as an MPLS VPN link in the Service Request process.
Network Topology
Figure 7-3 shows an overview of the network topology in which the MPLS VPN PE-CE links are created.
Figure 7-3 Network Topology for MPLS VPN PE-CE Scenarios.
The network topology in Figure 7-3 illustrates the lab environment of a service provider (Provider-X) and one customer (Cust-A). There is one Region (East-X) and one PE (mlpe3.cisco.com). Each customer device (one CE and one CLE) represents a Site (mlce11-Site and mlsw4-Site).
Prerequisite Tasks
Before you can create a Service Policy in ISC, you must complete the following Inventory Management tasks:
Step 1
Set up a Customer with a Site.
Step 2
Setup a Provider with a Region.
Step 3
Import, create, or discover Devices.
Step 4
Create CPE and PE.
Step 5
Collect Configurations.
Step 6
Create Resource Pools and CE routing communities (CERC).
Step 7
Define a VPN.

Defining a VPN for the PE-CE Link
During service deployment, ISC generates the Cisco IOS commands to configure the logical VPN relationships.
At the beginning of the provisioning process, before creating a Service Policy, a VPN must be defined within ISC. The first element in a VPN definition is the name of the VPN.
To create a VPN Name, follow these steps:
Step 1
Log in to ISC.
Step 2
Go to Service Inventory > Inventory and Connection Manager > VPNs.
The VPN window appears, as shown in Figure 7-4.
Figure 7-4 VPNs
Step 3
Click Create to create a VPN.
The Create VPN window appears, as shown in Figure 7-5.
Figure 7-5 Create VPN
Step 4
Edit the following attributes:
•
Name: Enter the vpn name. (east-xVPN)
•
Customer: Click Select.
The Select Customer window appears, as shown in Figure 7-6.

Step 5
Choose a customer and click Select.
Step 6
Click Save.
The VPNs window reappears, as shown in Figure 7-7.
