Add EVPN-VPWS Service Post Update Placements Parameters

You can configure placement parameters for the EVPN-VPWS 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.

Before adding the Update Placements parameters, you must create an EVPN-VPWS service instance and enter general, site, and site network access details about the service. See Add an EVPN Service Instance and Add EVPN-VPWS 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 verify placement parameters in the fields on the General page.

3. To add placement parameters on the General page:

   1. Expand Placement ESI (Ethernet Segment Identifier) to view and verify the allocated placement parameters on the EVPN ESI table.

      To edit the placement ESI parameters, select the name of the ESI and click the edit icon. The Placement ESI page appears. Edit the parameters by referring to the following table:

      Table 1: Placement ESI (EVPN-VPWS)

      Field	Description
      Name	Displays the name of the access diversity group to which the ESI ID is assigned.
      Pool	Select a pool from which the ESI is allocated.
      Values	Enter a value for the variable part of the ESI ID within the configured range. If you enter a value outside of the configured range, the page displays an error message. The variable part of the ESI ID is based on the Start and End values specified in the EVPN ESI section of the L2 Addr resource instance. For example, if you enter 00:01 as the Start value and 00:05 as the End value, the middle part of the ESI ID will be a value between 00:01 and 00:05.

   2. Expand Route Target to view and verify the placement parameters. You can edit the route target placements by referring to the following table:

      Table 2: Route Target (EVPN-VPWS)

      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.
      Pool	Select a pool value. The ASN values specified when configuring a VPN resource pool are available as options in the drop-down list.

   3. Expand Route Distinguishers to view and verify the assigned RDs. If you want to edit the RD placements:

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

         Configure the parameters by referring to the following table:

      Table 3: Route Distinguishers (EVPN-VPWS)

      Field	Description
      If you selected type0 as the Route Distinguisher Type:
      PE Node	The IP address or hostname 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. In the previous example, the number is 9.
      If you selected type1 as the Route Distinguisher Type:
      PE Node	The IP address or hostname 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 network implementation plan (NIP).
      Assigned Number	A unique number assigned to the RD by Routing Director from the block size configured in the NIP. 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.
