Provisioning Regular PE-CE Links

This chapter describes how to configure MPLS VPN PE-CE links in the IP Solution Center (ISC) provisioning process. It contains the following major sections:

• MPLS VPN PE-CE Link Overview

• Creating MPLS VPN PE-CE Service Policies

• Creating MPLS VPN PE-CE Service Requests

MPLS VPN PE-CE Link Overview

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 Service Inventory tasks:

Step 1 Set up a Customer with a Site (see Creating Customers, Sites, and CPEs).

Step 2 Setup a Provider with a Region (see Creating Providers, Regions, and PEs).

Step 3 Import, create, or discover Devices (see Creating Devices).

Step 4 Create CPE and PE (see Creating CPEs).

Step 5 Collect Configurations (see Collecting Configurations).

Step 6 Create Resource Pools (see Creating Resource Pools).

Step 7 Create CE routing communities (CERC) (see Creating CE Routing Communities).

Step 8 Define a MPLS VPN (see Creating an MPLS 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.

To define a VPN, perform the following steps:

Step 1 Choose Service Inventory > Inventory and Connection Manager > VPNs.

The VPN window appears.

Step 2 Click Create to create a VPN. The Create VPN window appears.

Step 3 In the Name field, enter the VPN name.

Step 4 In the Customer field, click Select.

The Select Customer window appears.

Step 5 Check to choose a Customer and click Select.

The VPNs window reappears where the new VPN Name is associated with a Customer in this new VPN definition.

Step 6 Click Save.

Creating MPLS VPN PE-CE Service Policies

This section contains the following sections:
