Add L3VPN Service Post Update Placements Parameters

You can configure placement parameters for the L3VPN service when you are creating or modifying the service instance. Use Update placements button on the Customer Site Settings page to automatically assign possible placement options for the service instance.

You must create an L3VPN service instance and add general, site, and site network access details before you update the placements parameters about the service. See Add an L3VPN Service Instance and Add L3VPN Site and Site Network Access Details.

To configure placement parameters:

1. Click the Update Placements button on top of the Customer Site Settings page and click Yes when prompted to confirm.

   The service instance is saved to the Routing Director database. The saved instance is listed in the Service Instances table on the Service Instances page.

   Service orchestration automatically assigns possible placement options such as PE devices and interfaces, CE devices, and VLANs for the service instance. After placement options are assigned, a confirmation message appears indicating that the placement was successfully updated.

2. Click Back on the Customer Site Settings page to configure placement parameters in the fields on the General page.

3. To add placement parameters on the General page:

   1. Expand Route Target and configure the placement parameters by referring to the following table:

      Table 1: Route Target

      Field	Description
      Number	Enter the number of route targets. The block size entered when configuring a VPN resource pool is the upper limit for the route target number. The entered block size is displayed to the right of the text box.
      Pool	Select a pool value. The ASN values specified when configuring a VPN resource pool are available as options in the drop-down list.

   2. Expand Route Distinguisher and configure the service instance to see the assigned RDs.

      Select the PE node and click the edit icon. The Route Distinguisher Type selected-type page appears.

      Configure the parameters by referring to the following table:

      If you selected type0 as the Route Distinguisher Type on the General page:
      PE Node	The name of the PE node device.
      Pool	The unique RD identifier configured as the ASN in the VPN resource pool. When the service is configured, the combination of the pool ID and a Routing Director assigned number is visible in the device CLI in the format pool:number. For example, 60000:9.
      Number	A unique number assigned to the RD by Routing Director.
      If you selected type1 as the Route Distinguisher Type on the General page:
      PE Node	Name of the PE node device.
      IP Address	Loopback address of the device. If you want to change the loopback address for the device, you can edit the entry from the available preconfigured loopback addresses. To edit, select the RD, click the pencil icon, and select another loopback address from the drop-down list.
      Name	Unique RD identifier populated from the configured names in the topo resource instance.
      Assigned Number	A unique number assigned to the RD by Routing Director from the block size configured in the topo resource instance. To change the assigned number, select the RD, click the pencil icon, and edit the number from the preconfigured range visible next to the textbox. When the service is configured, the combination of the loopback address and the assigned number is visible in the device CLI in the format loopback_IP:number. For example, 192.168.1.1:30.
