Creating a Multisegment Pseudowire Service Definition

 

To create an E-Line service definition for a multisegment pseudowire (MS-PW) service, complete these tasks, in the order shown:

Specifying General Information for the Multisegment Pseudowire Service

  1. In the Build mode of the Network Services > Connectivity task pane, select Service Design > Manage Service Definitions > New > E-Line Service Definition.

    The first Create E-Line Service Definition page appears.

  2. In the Name box, type a name for the service definition.
  3. Select the signaling type:

    • To create an FEC 128 MS-PW, select LDP.

    • To create an FEC 129 MS-PW, select BGP.

  4. Select the Pseudowire Type. By default, the Pseudowire Type for both LDP and BGP signalling type is Ethernet.
  5. Select the Instance Type. By default, the Instance Type is l2vpn.
  6. (Optional) In the Description box, type a brief description or other comment that you want to appear in the Service Definition table.
  7. Select the Service Extension options.

    • FEC 128—For signalling type LDP, select Enable Multi Segment Pseudowire service extension.

    • FEC 129—For signalling type BGP, when you select Enable Multi Segment Pseudowire service extension, another service extension option Enable Auto Discovery for MS-PW appears. Select both Enable Multi Segment Pseudowire and Enable Auto Discovery for MS-PW.

    Note

    If you select Enable PW Resiliency, you will be able to define pseudowire resiliency in the service order associated with this service definition.

  8. (Optional) To include a service template for the service, click the Add icon or plus sign (+) to select a service template from the Service Template list. The list of available service templates is displayed. Select the check box beside the template you want and click OK. You are returned to the General Settings page.

    The selected service template appears in the Default Service Template field.

    You can select one or more service templates as the default service template. By default, the default service templates are attached to the endpoints.

    Note

    You cannot add or delete a service template while creating a service order.

    The remaining service templates on the Service Template list are termed as optional service templates. You can attach the optional service templates to the endpoints on a need basis.

    In the View Service Definition Details page, the value for the default service template in the Default Service Template column is True.

    For instructions on creating a service template, see Creating a Service Template.

  9. Click Next to continue to the UNI Settings page.

Specifying UNI Settings for Multisegment Pseudowire

To specify the UNI settings for a multisegment pseudowire:

  1. Fill in the fields as indicated in Table 1.

    Table 1: UNI Settings for a Multisegment Pseudowire

    Field

    Action

    PE-CE Traffic Treatment

    Ethernet option

    Select an Ethernet option from the list.

    The Ethernet option you choose determines the other options you can select and specify on the page.

    Customer traffic type

    Select the Customer Traffic Type from the list. For port-to-port services, all traffic is always transported.

    VLAN Normalization

    Select a value:

    • Swap

    • Normalize to Dot1q—To transport only single-tagged frames across the network core. All port, dot1q , and Q-in-Q traffic is transported across the network.

    For more information on VLAN normalizations for LDP signalling type, see Table 2 .

    For more information on VLAN normalizations for BGP signalling type, see Table 3.

    Note: Starting with Release 1.0R2, when you newly install Connectivity Services Director, if you select the option to not require normalization in a service definition, the auto-pick option for VLAN IDs and the option to edit the auto-pick behavior in service order are disabled in the service definition. When you create a service order by associating with that service definition, you need to manually enter the VLAN IDs for the interfaces and cannot use the auto-pick functionality. This same behavior also applies to default service templates in which if you select the normalization-not-required functionality, the auto-pick option for VLAN IDs is disabled.

    For more information about VLAN normalization, see Junos Space Layer 2 Services Overview.

    For information about VLAN manipulation, see Understanding VLAN Manipulation (Normalization and VLAN Mapping) on Ethernet Services.

    Auto Pick VLAN ID

    Indicate how the VLAN ID is determined. By default, this check box is disabled.

    • Clear this check box to allow the service provider to specify the VLAN ID. This option is normally used when no VLAN normalization is applied. Specify the VLAN ID range in VLAN range for manual input.

      Note: Make sure to select Editable in Service Order if you want the service provisioner to be able to override this setting.

    • Select this check box when VLAN normalization is applied. Specify the VLAN ID pool in VLAN range for auto-pick.

      Note: Make sure to select Editable in Service Order if you want the service provisioner to be able to override this setting.

    Note: When the range of VLAN IDs that are automatically assigned by the system (with the auto-pick option enabled during the creation of a service definition) is less than or greater than the range of VLAN IDs that are manually specified (with the manual selection option enabled during the creation of a service definition), the following conditions apply during the creation of a service order with the Editable in Service Order check box selected during service definition creation:

    • If you create a service order with the auto-pick option enabled, the VLAN ID is selected from the auto-pick range, and the value is displayed in the VLAN range for manual input field. If you attempt to change the VLAN ID manually, the value is restricted to the manually configured range.

    • If you create a service order with the auto-pick option disabled, the VLAN ID is selected from the manually configured range, and the value is displayed in the VLAN range for manual input field. If you attempt to change the VLAN ID manually, the value is restricted to the manually configured range.

    VLAN ID range for auto-pick

    Enter the VLAN ID pool.

    Range: 1 through 4094

    VLAN ID range for manual input

    Enter the VLAN ID range.

    Range: 1 through 4094

    PE-CE Encapsulation

    Physical Interface

    Select the physical interface encapsulation method for the MS-PW.

    Logical Interface

    Select the logical interface encapsulation method for the MS-PW.

    PE-CE MTU Settings

    Editable in service order

    Select this check box to allow the service provisioner to override the MTU setting.

    Interface MTU (Bytes)

    The default MTU value is 1522 bytes. To allow the service provisioner to override the MTU setting, select the Editable in Service Order check box.

    MTU Range (Bytes)

    In the MTU range fields, enter the lowest and highest values for MTU for each UNI.

    Note: To allow the service provisioner to override the MTU setting, select Editable in Service Order and, in the MTU range fields, type the highest and lowest MTU values.

    PE-CE QoS

    Enable QoS

    When you enable QoS in the service definition, you can specify a QoS profile in the service order to classify traffic into defined service groups to provide the special treatment of traffic across the network service.

    For example, voice traffic can be sent across certain links, and data traffic can use other links.

    PE-CE Bandwidth

    Enable Rate Limiting

    To enable a service provisioner to limit the available bandwidth, select this check box, and type a default bandwidth limit.

    Note: Bandwidth settings are available in the service definition when Manage CoS Profiles page is configured with CoS profiles.

    Bandwidth (Mbps)

    Enter the default bandwidth value, in Mbps.

    Default: 10 Mbps

    Range: 1 Mbps through 100,000 Mbps

    Min Bandwidth (Kbps)

    To override the default bandwidth value, select the Editable in Service Order check box.

    Enter the minimum bandwidth value in Kbps.

    Default: 1000 Kbps

    Range: 64 Kbps through 100,000 Kbps

    Max Bandwidth (Kbps)

    Enter the maximum bandwidth value, in Mbps.

    Default: 100 Mbps

    Range: 1 Mbps through 100,000 Mbps

    Increment (Kbps)

    Enter a value in the range that is made available to the service provisioner.

    Burst Size

    Select the preferred option for calculating the burst size:

    • MTU Based

      If you select the option MTU Based, you can specify a value for MTU Factor in the range 1 through 1087902.

      The default value for MTU Factor is 10.

    • Line Rate Based

      If you select the option Line Rate Based, you can specify a value for Burst Period in the range 1 through 7450 milliseconds.

      The default value for Burst Period is 1.

    Note: The Calculate Burst Size list is enabled only when you select the Enable rate limiting check box.
