Provisioning Multi-VRFCE PE-CE Links

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

MPLS VPN MVRFCE PE-CE Link Overview

This section contains the following sections:

• Network Topology

• Prerequisite Tasks

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 an MVRFCE PE-CE. The following scenarios focus on the MVRFCE PE-CE Policy Type.

An MVRFCE PE-CE Policy Type is a PE to CE link with three devices:

•PE

•Multi-VRF CE

•CE

This Policy Type has two options:

•CE Present enabled (One PE with one MVRFCE and one CE; three devices)

•CE Present disabled (One PE with one MVRFCE; two devices)

Figure 8-1 shows an example of an MVRFCE PE-CE link with three devices.

Figure 8-1 MVRFCE PE-CE Link

In an MVRFCE PE-CE link with CE Present enabled, interfaces FE 0/0, E 0/1, E 0/2 and FE 0/1 are configured as an MPLS VPN link in the Service Request process.

Figure 8-2 shows an example of a PE to MVRFCE link with no CE.

Figure 8-2 MVRFCE PE-CE Link with No CE

In an MVRFCE PE-CE link with CE Present disabled, interfaces FE 0/0, E 0/1, and E 0/2 are configured as an MPLS VPN link in the Service Request process.

Network Topology

Figure 8-3 shows an overview of the network topology in which the MPLS VPN MVRFCE PE-CE links are created.

Figure 8-3 Network Topology for MPLS VPN MVRFCE PE-CE Scenarios

The network topology in Figure 8-3 illustrates the lab environment of a service provider (Provider-X) and one customer (Cust-A). There is one Region (West-X) and one PE (mlpe2.cisco.com). Each customer device (one MVRFCE and one CE) represents a Site (mlce3-Site and mlce4-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 (see Creating Customers, Sites, and CPEs).

Step 2 Setup a Provider with a Region (see Creating a Provider).

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 VPN for MVRFCE PE-CE Links

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, 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 Edit the following attributes:

•Name: Enter the VPN name.

•Customer: Click Select.

Step 4 Choose a Customer and click Select.

Step 5 Click Next.

The VPNs window reappears showing that the VPN Name is associated to the Customer in this new VPN definition.

Creating an Unmanaged MVRFCE

The unmanaged MVRFCE feature is similar to the unmanaged CE feature in so far as the service provider does not use ISC to upload or download configurations to the CPE. This feature is similar to the managed MVRFCE feature in so far as ISC creates a link with three devices: a PE, an MVRFCE, and a CE.

In the unmanaged scenarios, the customer configures the CPE manually. To automate the process of configuring the unmanaged MVRFCE, the service provider can use ISC to generate the configuration and then send it to the customer for manual implementation.

Figure 8-23 shows an overview of a network topology with MPLS VPN MVRFCE PE-CE links.

Figure 8-23 Unmanaged MVRFCE PE-CE Network Topology

The network topology in Figure 8-23 shows a service provider (Provider-X) and a customer (Cust-A). The Provider contains one Region (West-X) and one PE (mlpe2). The Customer contains an MVRFCE (mlce3) and a CE (mlce4). Both of these CPEs are unmanaged.
