Creating an E-Line Multisegment Pseudowire Service Order

Selecting the Service Definition

1. Select Service View from the View Selector. The workspaces that are applicable to routing and tunnel services are displayed.
2. From the Connectivity Services Director user interface, click the Deploy icon in the Connectivity Services Director banner. The functionality that you can configure in this mode are displayed in the task pane.
3. From the View pane, click the plus sign (+) to expand the tree and select the type of service.
4. From the Tasks pane, select Service Provisioning > Manage Services.

   The Manage Network Services page is displayed in the top half of the right pane, which displays all of the configured services. The Manage Service Orders page is displayed in the bottom half of the right pane, which displays all of the service orders corresponding to a service.

   From the Manage Network Services page, select New > E-Line Service Order.

   The Create E-Line Service Order page displays an inventory of all available E-Line service definitions.

   The General/Connectivity Settings panel appears initially in the right panel.

   Note

   In the service order creation wizard for E-Line services, the search function has been enhanced to enable you to easily sort and filter the parameters that are of interest and relevance for the services you want to configure. The Choose Customer dialog box that is displayed when you click Select beside the Customer field contains the Search box, which enables you to perform a search on all of the columns. The search utility that is present in the Choose Service Definition dialog box that is displayed when you click Select beside the Service Definition field enables you to search by Name, Created by, and Signaling columns; search utility is not supported for other columns in the dialog box. The search box that is present in the Choose Endpoints dialog box when you click Select beside the PE Device and UNI Interface fields enables search across all the columns displayed in the dialog box. For any string-based search (which shows strings that match any part of the text you enter in the search box), only the Name, Platform, and OS Version columns are supported. For exact string-based search (which shows strings that exactly match the text you enter in the search box), the IPAddress, State, and Manage State columns are supported.

5. From the Service Definition field, click Select to choose the service definition you want to base your service order on. The Choose Service Definition inventory page displays a view of only those published service definitions designed to work with the type of services you need.

   Based on the fields or parameters that you defined in the service definition to be enabled for modification in the service order, the corresponding fields are available for editing. The fields that are disabled for modification in the service order can only be edited in the service definition.

6. Select the check box beside the service definition that you want to associate with the service order, and click OK.
7. Click View to open a popup dialog box that displays the details of the selected service definition. The service definition properties, such as the name, signaling type (LDP or BGP), service type (Ethernet, ATM, or TDM), are displayed. The interface-specific attributes, such as rate-limiting details, encapsulation, and VLAN tags, are also displayed in the dialog box. Close the dialog box to return to the service order creation wizard.

   If a template is attached to the service definition on which the service order is based, you can invoke the template editor from the Template page of the wizard.

Entering General/Connectivity Settings Information

The General Settings panel is displayed on the right side of the service order window.

To configure general settings in the General Settings/Connectivity Settings panel, provide the following information:

1. In the Name box, enter a unique name for the service.

   The service order name can consist of only letters, numbers, and underscores.

   Note

   The name you specify for a service order becomes the routing-instance name in the device configuration when you deploy the service. Consequently, you cannot use any Juniper Networks keywords, for example, “bgp” or “vpls”, as the name of a service order.

2. (Optional) In the Comments box, enter a description of the service. This description appears in information windows about the request or service instance created from the request.
3. In the Customer box, select the customer requesting the service.

   If the customer is not in the list, you must add the customer to the database before proceeding. See Adding a New Customer.

4. (Optional) Select the LSP Association check box to associate an existing LSP.Note

   The Enable LSP Association check box is not available on the General Settings page if the signaling type is LDP.

   Select the Create LSP check box to import an existing LSP service definition and also select an LSP name pattern.

   Note

   You can also create an LSP name pattern of your preference, instead of using an existing pre-defined pattern.

   For information about creating an LSP name pattern, see Creating a Name Pattern for LSPs in the Service Order.

5. In the Connectivity Settings box, specify the MTU for the connection across the network.

   The service definition can constrain the MTU to a specific value or allow the service provisioner to override it in the service order. In this example, the service definition sets the MTU, but allows the service provisioner to change the value.

   When you advance to the next step in creating your service order, your new connectivity settings appear under the Connectivity image in the main graphic and new general information is added to the text above the cloud. If you have incomplete or invalid information in the General/Connectivity Settings panel, a warning icon appears next to the cloud image.

6. Enter the virtual circuit identifier (VCID). This integer uniquely identifies the virtual circuit that the service uses.

   The VCID can be set either automatically by the Junos Space software by selecting Auto Pick VC ID, or the service provisioner can set it manually in the service order. The service definition can force the system to pick the VCID, force the service provisioner to pick the VCID, or allow the service provisioner to override the settings in the service definition.

   We recommend allocating the VCID automatically; however, service providers with their own systems for allocating VCIDs can choose the manual setting.

   By default, the system picks a VCID from its pool automatically, but allows the service provisioner to override this value in the service order. The form expands to include an additional field for typing the VCID manually.

   This field is displayed only if the selected definition’s signaling type is LDP. You cannot edit this field if you have not selected the Editable in Service Order in the service definition.

7. Select a CFM profile that you want to associate with the E-line MS-PW. The CFM profile is propagated to a single endpoint when multiple interfaces are selected for a given device (the last interface overrides the other configurations).
8. Provide endpoint information for the first endpoint: click the Endpoint A Setting graphic element or click Next.

   The Endpoint A Settings form appears in the right panel.

Specifying Endpoint A Information

1. In the Endpoint A box, click Select to choose the N-PE device you want to use as Endpoint A. From the Choose Endpoints dialog box that appears, select the devices that you want to participate in the service. Use the multiple selection feature to select one or more devices. The lower part of the dialog box refreshes to display the interfaces associated with the selected device. Select the check boxes next to the interfaces you want to associate with the service order.Note

   In the Choose Endpoints dialog box, you can sort and segregate the devices and their corresponding interfaces based on the roles of the devices to easily and quickly view only the devices of interest. Click the down arrow on the Filter Role menu, and select P2E to view only the provider edge devices, P to view only the provider devices, and L2E to view only Layer 2 Ethernet devices.

   If you are unsure about which PE device to choose, go to the Prestaging Devices workspace landing page, which shows capacity information about UNIs on PE devices. You must pick a device that has available UNIs.

   This step is required for all service orders.

   Based on the device selected, the rest of the fields such as UNI Interface, Physical IF encapsulation, Logical IF encapsulation, and Traffic Type on the Endpoint A Settings page are automatically populated.

2. If you have selected Enable PW Resiliency in the selected service definition, select a backup by clicking Backup Settings A. Provide required information for the LSP Name, Revert time (sec), and Switch Over Delay (sec) fields.
3. Based on the type of Physical IF encapsulation, the corresponding fields are displayed. For example, if the Physical IF encapsulation is vlan-ccc, the following fields are displayed. Enter the required information.Note

   You cannot change the type of Physical IF encapsulation and the Logical IF encapsulation. These values are set in the service definition.

   • Unit ID—Enter the logical unit identifier of the service.

   • VLAN ID—Enter the VLAN identifier of the service.

   • LSP Name—Select the LSP tunnel you want to use for this device. This field is displayed only if the selected definition’s signaling type is LDP.

   • COS Profile—Enter the name of the COS profile that you want to associate with the service.

   Note

   These fields are editable if you have selected the Editable in Service Order check box in the service definition.

   Based on the device selected, the rest of the fields such as UNI Interface, Physical IF encapsulation, Logical IF encapsulation, and Traffic Type on the Endpoint A Settings page are automatically populated.

2. If you have selected Enable PW Resiliency in the selected service definition, select a backup by clicking Backup Settings Z. Provide required information for the LSP Name, Revert time (sec), and Switch Over Delay (sec) fields.
3. Based on the type of Physical IF encapsulation, the corresponding fields are displayed. For example, if the Physical IF encapsulation is vlan-ccc, the following fields are displayed. Enter the required information.Note

   You cannot change the type of Physical IF encapsulation and the Logical IF encapsulation. These values are set in the service definition.

   • Unit ID—Enter the logical unit identifier of the service.

   • VLAN ID—Enter the VLAN identifier of the service.

   • LSP Name—Select the LSP tunnel you want to use for this device. This field is displayed only if the selected definition’s signaling type is LDP.

   • COS Profile—Enter the name of the COS profile that you want to associate with the service.

   Note

   These fields are editable if you have selected the Editable in Service Order check box in the service definition.

4. • In the service definition, if the following conditions are set, the next tab is Stitching Endpoint(s) Setting. Click Stitching Endpoint(s) Setting graphic element or click Next to stitch the MS-PW.

     • Signalling type is BGP,

     • Enable Multi Segment Pseudowire is selected, and

     • Enable Auto Discovery for MS-PW is not selected.

   • In all other cases, the next tab is Review. Click Review graphic element or click Next to review your service order.

Specifying Stitching Endpoint(s) Settings

1. The UNI Settings section displays the UNI settings that has been set in the service definition. You can update the UNI settings if you choose to do so.
2. The table displayed on the lower part of the page lists the devices that you have selected as endpoints A and Z. Endpoint A is displayed under Source Device > Primary. Endpoint B is displayed under Destination Device > Device Name. In the service definition, if the signalling type is LDP and Enable PW Resiliency option is selected, the backup device details that you provided for endpoint A is populated under Source Device > Backup. The backup device details that you provided for endpoint Z is populated in the last entry of the grid's destination device backup.

   You can now select the segments that you want to configure between endpoint A and endpoint Z. To select segments:

   1. In the row that displays the first primary device, click Device Name under Destination Device.

      A pop-up screen appears displaying a list of devices that you can select.

   2. Select a device that you want to add as a segment.

      The selected device appears under Destination Device > Device Name. It will also appear under Source Device > Primary. So effectively this segment connects endpoint A to endpoint Z.

   3. Select an interface for the segment by clicking Interface and selecting an interface from the pop-up screen that appears.

      The selected interface appears under Destination Device > Interface.

      Note

      The segment can only have an lt or iw interface.

   4. (Optional) Select a backup for the segment by clicking Destination Device - Backup > Device Name.

      A pop-up screen appears displaying a list of devices that you can select. Select a device that you want to add as a segment backup.

   5. Enter values for Unit and Peer Unit for the segment under Destination Device > Unit and Destination Device > Peer Unit respectively.

      Note

      You have to configure the unit and peer unit only for segments, and not for the endpoints.

3. Click Review graphic element or click Next to review your service order.
