Provisioning Multi-VRFCE PE-CE Links
This chapter describes how to configure MPLS VPN Multi-VRFCE PE-CE links in the Prime Fulfillment provisioning process.
MPLS VPN MVRFCE PE-CE Link Overview
This section contains the following sections:
•Network Topology
•Prerequisite Tasks
To provision an MPLS VPN service in Prime Fulfillment, you must first create an MPLS VPN Service Policy. In Prime Fulfillment, a Service Policy is a set of default configurations for creating and deploying a service request. Prime Fulfillment 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 26-1 shows an example of an MVRFCE PE-CE link with three devices.
Figure 26-1 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 26-2 shows an example of a PE to MVRFCE link with no CE.
Figure 26-2 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 26-3 shows an overview of the network topology in which the MPLS VPN MVRFCE PE-CE links are created.
Figure 26-3 Network Topology for MPLS VPN MVRFCE PE-CE Scenarios
The network topology in Figure 26-3 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 Prime Fulfillment, you must complete the following Inventory Management tasks:
Step 1 Set up a Customer with a Site (see Chapter 21, "Creating Customers, Sites, and CPEs").
Step 2 Setup a Provider with a Region (see Chapter 21, "Creating a Provider").
Step 3 Import, create, or discover Devices (see Chapter 21, "Creating Devices").
Step 4 Create CPE and PE (see Chapter 21, "Creating CPEs").
Step 5 Collect Configurations (see Chapter 21, "Collecting Configurations").
Step 6 Create Resource Pools (see Chapter 21, "Creating Resource Pools").
Step 7 Create CE routing communities (CERC) (see Chapter 21, "Creating Route Target(s)").
Step 8 Define a MPLS VPN (see Chapter 21, "Creating an MPLS VPN").
Defining VPN for MVRFCE PE-CE Links
During service deployment, Prime Fulfillment 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 Prime Fulfillment. 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 Inventory > Logical Inventory > VPNs.
The VPNs window appears.
Step 2 Click Create to create a VPN.
The Create New VPN window appears.
Step 3 Edit the following attributes:
•Name: Enter the VPN name.
It is recommended not to use special characters (' ` " < > ( ) [ ] { } / \ & ^ ! ? ~ * % = , . + |) in the VPN name, as this may cause misconfiguration of the VRF name for certain devices, if the VPN name is used to autogenerate a VRF name.
•Customer: Click Select.
The Select Customer window appears.
Step 4 Choose a Customer and click Select.
Step 5 Click Save.
Note Independent VRF association is not supported for MVRFCE-based policies and service requests.

The MPLS Service Requests window reappears showing that the MPLS VPN MVRFCE PE-NoCE service request is in the Requested state and ready to deploy.
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 Prime Fulfillment to upload or download configurations to the CPE. This feature is similar to the managed MVRFCE feature in so far as Prime Fulfillment 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 Prime Fulfillment to generate the configuration and then send it to the customer for manual implementation.
Figure 26-13 shows an overview of a network topology with MPLS VPN MVRFCE PE-CE links.
Figure 26-13 Unmanaged MVRFCE PE-CE Network Topology
The network topology in Figure 26-13 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.
