Network Topology

Prerequisite Tasks

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.

VPN

Definition: east-xVPN

See: Defining a VPN for the PE-CE Link

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.
