Provisioning Layer 2 VPN Pseudowires

Pseudowire provisioning is the process of creating, modifying, or deleting pseudowires between end points and pushing the configurations corresponding to the pseudowire to the devices.

To provision a Layer 2 VPN pseudowire, follow these steps:

  1. In the Junos Scope main window, click Provisioning > Pseudowires > Provisioning L2VPN Pseudowires. The Select Device Source dialog box appears. Here you can select a device group from a list of device groups that were already created by selecting the radio button "Select device groups". Alternatively, you can create device groups by grouping devices dynamically based on one of the following filtering criteria: location, name, hostname, or model.

    You can also directly select devices from the list in the Select Devices Directly radio button. In this case, all devices that have been added to Junos Scope are listed in the Select Devices list.

  2. Select an option button to specify whether you wish to Select Devices Directly or Select a Device Group.
  3. If you choose to select devices directly, you can either select the devices from the Select Devices list or filter the list of devices to generate a subset of devices based on the criterion of your choice. To filter the list of devices:
    1. From the Select a Field drop-down list, select one of the following options: Device Name, Device Hostname, Model, Location, and Comment.
    2. From the Select an Operator drop-down list, select one of the following options: Contains, Does not contain, Starts With, Ends With, and Equals.
    3. Enter a string and click View to display a list of devices that meet your criteria.

    For example, to list devices that have device names starting with J, select Device Name from the Select Field drop-down list, select Starts With from the Select an Operator drop-down list. Enter J in the text box, and click View. All devices that have device names starting with J will be listed in the Select Devices list.

  4. Click Next. The Add/Edit/Delete Pseudowire dialog box opens. Pseudowires that are already provisioned or newly created for provisioning for the devices that were selected in the previous step are shown at the bottom.

  5. Enter the name of the VPN Name field.
    If it is not specified, a VPN name is automatically generated for the pseudowire.
  6. Select the Source Device Name and Destination Device Name.
  7. Select the type of interface you want to use from the Interface Type list. The options are: TDM (SAToP), ATM, and Ethernet
  8. Select a Template from the drop-down list. The templates in the drop-down list depends on the interface type that you have selected.

    If the template type is ATM II, specify the VCI and VPI . These are the same for both endpoints.

    If the interface type is Ethernet, specify the VLAN ID. VLAN ID is the same for both endpoints.

  9. Enter a value in the Route Distinguisher field. The route distinguisher is used to place bounds around a VPN so the same IP address prefixes can be used in different VPNs.
  10. Enter a value in the VRF Community field. The syntax for the VRF community is not a name. You must specify it in the format target:x:y.
  11. For the Source Endpoint and Destination Endpoint, specify the following:
    1. Device Name
    2. CE Interface: CE-facing interface. The drop-down lists the interfaces available for the endpoints specified.
    3. Logical Unit (number): The default value is 0. If you do not specify a value, the system automatically assigns a unique logical unit based on the pseudowires that were already provisioned.
    4. Enter Site Name and Enter Site ID: Enter the name and ID of the VPN site.
  12. Click Add Entry. The pseudowire is listed at the bottom of the screen.

    The table at the bottom of the screen displays:

    • State: State can be one of the following:
      • New: If the pseudowire is new.
      • Modified: If an exiting pseudowire is modified.
      • Unchanged: If an existing pseudowire is unchanged.
    • VPN Name
    • Source Device Name
    • Source CE Interface
    • Destination Device Name
    • Destination CE Interface
  13. To view a pseudowire, select an existing record from the list and click View.
    To modify a pseudowire, select an existing record from the list and click Edit.

    To delete a pseudowire, select an existing record from the list and click Delete.

    Select a pseudowire from the list and click Force Edit to forcefully edit the pseudowire configuration on devices without making any modifications to the pseudowire configuration. The State field will be displayed as if it were modified even though no change was made to the pseudowire.

  14. Click Next. The Confirm Add/Edit/Delete Pseudowires dialog box opens.

    Click Previous to return to Add/Edit/Delete Pseudowires dialog box.

    Select when you want to push the configurations that were generated for the pseudowires to the devices:
    • Now—(Default) Pushes the configuration to the device immediately after you confirm it.
    • Save Operation as—Saves the current operation so you can run that operation at a later time. Click Save Operation as, then type an operation name in the text box.
    • Select Schedule—Pushes the configuration to the device at the scheduled time interval. Select the schedule that you want in the schedule table.
  17. Click OK. You can go back to the previous step at any time by clicking Previous.
