Add an L2 Circuit Service Instance

As a superuser or network administrator, you can use Paragon Automation to provision Layer 2 (L2) circuit services in your network. An L2 circuit is a virtual point-to-point L2 connection between two CE devices through a packet-switched network such as Multiprotocol Label Switching (MPLS), in the service provider's network. The CE devices running the same L2 protocol (such as Ethernet) connect to PE devices in the service provider network through a physical or logical attachment circuit.

Note:

  • LDP signaling without BGP autodiscovery is the only variant of L2 Circuit that is supported in this release.

  • Redundant pseudowires for L2 Circuit are not supported in this release.

When you create and save an L2 circuit service instance, Paragon Automation generates a create service order. After you provision the service instance, Paragon Automation activates the automated workflow for fulfilling the service order and provisions the service in the network.

To create an L2 circuit service instance, either upload a preconfigured JSON file or enter the details in the GUI fields on the Add L2 Circuit page.

To create an L2 circuit service instance:

  1. Click Orchestration > Instances.

    The Service Instances page appears.

  2. Click Add > L2 Circuit.

    The Add L2 Circuit Service page appears.

  3. In the General section, enter the values by referring to Table 1.
  4. Click Next to proceed to the VPN Nodes section.
  5. Enter VPN node details in the VPN Nodes section. See Add L2 Circuit VPN Nodes.
  6. Click Next to proceed to the Summary section.
    You see a graphical map of your service topology and a summary of the instance details. Zoom in and out using the zoom icons on the map.
  7. (Optional) Click Export to export and save the service details in JSON format on your local system.
  8. Click Next to proceed to the Schedule section.
  9. (Optional) Switch the Schedule toggle on if you want to schedule when to provision the service. The Schedule option is disabled by default.

    The Schedule field appears. Perform the following steps to schedule the date and time to provision the service:

    1. Click the calendar icon in the Schedule field.
    2. Select the date and time for provisioning the service, and click OK.
      The scheduled date and time are displayed in the MM/DD/YYYY HH:MM AM/PM format.
      Note:

      • You must set a present or future date and time to schedule provisioning of a service. If you select a past time and save the service order, the service is provisioned immediately.

      • To delete a provisioning schedule, select the service-instance-name on the Service Instances page and click the edit icon. On the Modify Service-Instance-Name page, proceed to the Schedule section. In the Schedule section, switch the Schedule toggle off and click Save. The provisioning schedule is deleted and the service instance is provisioned immediately.

  10. To save and provision the service instance, click one of the following buttons:

    • Save & Provision—Click this button and confirm when prompted, to save the service instance to the Paragon Automation database and provision the instance immediately. Selecting this option discards any provisioning schedule that you configured, and provisions the service immediately.

    • Save—Click this button to save the service instance to the Paragon Automation database. The Service Instances page appears and the new service instance is listed in the Service Instances table. To provision the service instance, select the service instance name and click Provision. Alternatively, you can schedule provisioning of the service instance as defined in step 9.

      Note:

      • The Provision button is disabled if you schedule the provisioning of a service instance. The service is provisioned automatically at the scheduled date and time.
