Creating a Point-to-Point Ethernet Service Definition

This procedure provides the steps to create a definition for a point-to-point VPN service. The standard service definitions that came with your initial software installation are designed to be appropriate for most requirements. You can also create a customized service definition—for example, to set different bandwidth limits on the service than those offered in the standard service definitions.

Once the new service definition is complete and published, network operators or service provisioners can use the completed service definition as a base for creating and then activating point-to-point VPN services on the network.

The screens appear in the order stated. You can, however, perform these steps in any order by accessing them through the task list in the right panel. If the panel is not visible, click the snap tool on the right side of the main display area.

To create a point-to-point service definition, follow these procedures:

  1. Specifying General Information
  2. Specifying Connectivity Information
  3. Specifying UNI Settings

Specifying General Information

To specify the general information for a point-to-point Ethernet (LDP) service definition, follow these steps:

  1. In the task ribbon, select Service Design > Manage Service Definitions > Create P2P Service Definition.

    The first Create Service Definition screen appears, as shown in the following example:

  2. In the Name field, enter a name for the service definition.
  3. In the Comments field, enter a brief description or other comment that you want to appear in the Service Definition table. (Optional)
  4. To enable QoS on the service, select the checkbox Enable QoS.

    When you enable QoS in the service definition, you must 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.

  5. Click Next to save the General step information. The Connectivity step appears.

Specifying Connectivity Information

In the Connectivity step, specify the attributes that define the connectivity between remote sites across the service provider network. An example screen follows:

To specify connectivity between sites across the network, follow these steps:

  1. In the VC ID selection field, specify how the VC ID will be chosen during service order creation:
    • To allow the service provisioner to enter the VC ID, choose Select manually.
    • To cause the Junos Space software to assign a VC ID automatically from the VC ID pool, select Auto pick.

    To allow the service provisioner to override the setting in the VC ID field, select Editable in service order.

  2. In the Default MTU field, specify the MTU across the service provider network.

    To allow the service provisioner to override the MTU setting, select Editable in service order. In the MTU range field, enter the highest and lowest MTU that the service provisioner can enter.

  3. Click Next to save the connectivity settings. The UNI Settings step appears.

Specifying UNI Settings

In the UNI Settings step, provide the UNI service attributes for this service definition. The attributes you set depend on whether you are setting attributes for a port, an 802.1Q interface, or a Q-in-Q interface.

Specifying UNI Settings for Port-to-Port Services

To set UNI attributes for a port:

  1. In the Ethernet option field, select port-port. The screen shows options specific to port-to-port circuits, as shown in the following example:
    Image s600888.gif

  2. In the Customer traffic type field, select N/A. For port-to-port services, all traffic is always transported.

    The VLAN ID cannot be selected. In port-to-port services, all traffic and all VLANs on one port are transported to the other port.

  3. In the Physical IF encapsulation field, select ethernet-ccc, which is the only valid physical interface encapsulation method for port-to-port services.

    The Logical IF encapsulation field cannot be selected because it is not relevant to port-to-port services.

  4. In the Default MTU field, specify the MTU for each UNI.

    To allow the service provisioner to override the MTU setting, select Editable in service order. In the MTU range field, enter the highest and lowest value for MTU that the service provisioner can enter.

  5. To enable a service provisioner to limit the available bandwidth, select Enable rate limiting and enter a default bandwidth limit.

    To enable the service provisioner to override the default bandwidth value, select the Editable in service order checkbox. The Bandwidth Range (Mbps) and Increment (Mbps) fields become active.

    • In the Bandwidth range (Mbps) fields, enter the lowest and highest values that the service provisioner can enter.
    • In the Increment (Mbps) field, enter a value that defines which values in the range will be made available to the service provisioner. For example, a range of 10 through 50 with an increment of 10 makes the following values available to the service provisioner: 10, 20, 30, 40, and 50 Mbps.
  6. Click Finish to save the UNI settings.

    The service definition is complete.

Specifying UNI Settings for Services with 802.1Q Interface Types

To set UNI attributes for 802.1Q interfaces:

  1. In the Ethernet option field, select dot1q. The screen shows options specific to 802.1Q interfaces, as shown in the following example:
    Image s600889.gif

  2. In the Customer Traffic type field:

    • Select Transport single vlan to transport the traffic for specific VLANs across the network.

      The service provisioner will be prompted for the VLAN-ID when creating a service order based on this service definition.

    • Select Transport vlan range if you want to limit the traffic across the network to a specific range of VLANs.

      If you select this option, the service provisioner will be prompted for the VLAN-ID range when creating a service order based on this service definition.

  3. In the VLAN ID field, specify how the VLAN ID will be determined:
    • To allow the service provider to specify the VLAN ID, choose Select manually.

      To enable the service provisioner to override this setting, select Editable in service order.

      Select manually is the only available option when you select Transport vlan range.

    • To cause the VLAN ID to be selected automatically from the VLAN ID pool, select Auto pick.

    To enable the service provisioner to override this setting in a service order, select Editable in service order.

  4. In the Physical IF encapsulation field, select the default physical encapsulation scheme to be used by service orders based on this service definition. We recommend you select flexible-ethernet-services.
  5. The Logical IF encapsulation field is constrained by your selection in the Physical IF encapsulation field. If you selected the recommended physical encapsulation mode of flexible-ethernet-service, then your only option is to select vlan-ccc for the logical encapsulation method.
  6. In the Default MTU field, specify the MTU for each UNI.

    To allow the service provisioner to override the MTU setting, select Editable in service order and, in the MTU range fields, enter the lowest and highest values for MTU that the service provisioner is allowed to enter.

  7. To enable a service to limit the available bandwidth, select Enable rate limiting and enter a default bandwidth limit in the Default bandwidth (Mbps) field.

    To enable the service provisioner to override the default bandwidth value, select the Editable in service order checkbox. The Bandwidth Range (Mbps) and Increment (Mbps) fields become active.

    • In the Bandwidth range (Mbps) fields, enter lowest and highest values that the service provisioner can enter.
    • In the Increment (Mbps) field, enter a value that defines which values in the range will be made available to the service provisioner. For example, a range of 10 through 50 with an increment of 10 makes the following values available to the service provisioner: 10, 20, 30, 40, and 50 Mbps.
  8. Click Finish to save the UNI settings.

    The service definition is complete.

Specifying UNI Settings for Services with Q-in-Q Interface Types

To set UNI attributes for Q-in-Q interfaces:

  1. In the Ethernet option field, select qinq. The screen expands to include options specific to Q-in-Q interfaces, as shown in the following example:

  2. In the Customer traffic type field:
    • Select Transport all traffic if you want to transport the traffic from all VLANs across the network.
    • Select Transport single vlan to transport the traffic for specific VLANs across the network.

      The service provisioner will be prompted for the VLAN-ID when creating a service order based on this service definition.

    • Select Transport vlan range if you want to limit the traffic across the network to a specific range of VLANs.

      If you select this option, the service provisioner will be prompted for the VLAN-ID range when creating a service order based on this service definition.

  3. In the VLAN ID selection field, specify how the service provider VLAN ID will be set during service order creation:
    • To cause the provisioning software to automatically select the service provider VLAN ID from the VLAN ID pool, select Auto pick.
    • To allow the service provisioner to specify the service provider VLAN ID, choose Select manually.

    To enable the service provisioner to override this setting, select Editable in service order.

  4. In the Physical IF encapsulation field, select the default physical encapsulation scheme to be used by service orders based on this service definition. We recommend you choose flexible-ethernet-services.
  5. The Logical IF encapsulation field is constrained by your selection in the Physical IF encapsulation field. If you selected the recommended physical encapsulation mode of flexible-ethernet-services, then your only option is to select vlan-ccc for the logical encapsulation method.
  6. In the Default MTU field, specify the MTU for each UNI.

    To allow the service provisioner to override the MTU setting, select Editable in service order and, in the MTU range fields, enter the lowest and highest values for MTU that the service provisioner can enter.

  7. To enable a service to limit the available bandwidth, select Enable rate limiting and enter a default bandwidth limit in the Default bandwidth (Mbps) field.

    To enable the service provisioner to override the default bandwidth value, select the Editable in service order checkbox. The Bandwidth Range (Mbps) and Increment (Mbps) fields become active.
