Add L3VPN Service Post Update Placements Site Network Access 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 General page and 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 on the Site Network Access table. After placement options are assigned, a confirmation message appears indicating that the placement was successfully updated.

    The Site Network Access table contains the fields required to provision services between customer sites and the service provider network. The fields in the Site Network Access table are populated with the configuration you enter in the Network Implementation Plan and the Customer Site Settings page when you configure the service.

    For information on each field, see Fields in the Site Network Access table

    Table 1: Fields in the Site Network Access table
    Field Description
