Example: Configuring and Deploying an E-Line Service

This example deploys and verifies an E-Line service starting with two MX Series devices. Figure 1 shows the service.

Figure 1: Simple E-Line Service

This service provides connectivity for one VLAN, using 802.1Q interface endpoints. Customer site A connects to the network through UNI ge-0/0/2 on an N-PE device named SJC. Customer site B connects to the network through UNI ge-0/0/3 on an N-PE device named SFO.

The bandwidth for each UNI is limited to 1000 Mbps.

You can create this service by performing the following tasks, in order:

Preparing Devices for Discovery

Before you can add a device using device discovery, the following conditions must be met:

• SSH v2 is enabled on the device. To enable SSH v2 on a device, issue the following CLI command:

  set system services ssh protocol-version v2

• The NETCONF protocol over SSH is enabled on the device. To enable the NETCONF protocol over SSH on a device, issue the following CLI command:

  set system services netconf ssh

• The device is configured with a static management IP address that is reachable from the Junos Space server. The IP address can be in-band or out-of-band.

• A user with full administrative privileges is created on the device for the Junos Space administrator.

• If you plan to use SNMP to probe devices as part of device discovery, ensure that SNMP is enabled on the device with appropriate read-only V1/V2C/V3 credentials.

Discovering Devices

Device discovery is a process that Junos Space uses to bring network devices under its control. This example brings two MX Series routers under Junos Space management:

1. Log in to Junos Space using your credentials.
2. From the Junos Space Network Management Platform user interface, select Devices > Discover Devices > Discover Targets.
3. In the Discover Targets window, click +.

   The Add Device Target window appears.

   
   
   
4. Select IP range.
5. Enter the IP address information. This example uses a range of two addresses.
6. Click Add, and then click Next.
7. In the Devices: Specify Probes window, select both Ping and SNMP as probes.
8. Click Next.
9. In the Devices: Specify Credentials window, click + and enter the device login credentials.
10. Click Finish.

    Device discovery begins. It displays a graph showing the status of the discovery operation. Initially, two devices are discovered. When Junos Space has accessed both devices and brought them under its management, both devices move from the Discovered column of the graph to the Managed column.

11. To check the results of the device discovery operation, select the Devices workspace again, then select Device Management. The Manage Devices page shows the added devices.
    
    

Preparing Devices for Prestaging

Before prestaging devices for E-Line services, the following entities must be configured:

• MPLS must run on each N-PE device.

• LDP signaling must be established between N-PE devices that you want to participate in the same E-Line service.

To satisfy these configurations, ensure that the following configuration exists on each N-PE device:

Discovering and Assigning N-PE Roles

Before you can provision services, you must prestage the devices. Prestaging includes assigning device roles and designating interfaces on those devices as UNIs. This example provides the steps to accept the recommendations of the Network Services application for N-PE devices and UNIs.

1. From the View selector, select Service View. The workspaces that are applicable to routing and tunnel services are displayed.
2. Click the Build icon in the Service View of the Connectivity Services Director banner. The functionalities that you can configure in this mode are displayed in the task pane.
3. In the Network Services > Connectivity task pane, select Prestage Devices > Prestage Devices.

   View the values displayed under the Roles column of the discovered devices.

   This action launches the role discovery process in which the Network Services application examines the devices under Junos Space management looking for devices that match predefined rules that identify N-PE devices. In this example, the Role Discovery Status graph shows that the Network Services application has discovered two such devices.

4. Click Manage Device Roles and from the drop-down list, select Discover Roles to retrieve the roles of the devices. A dialog box is displayed with the job ID of the discovery job that is created to obtain the latest roles of the devices.
5. To view the assignment status, in the CSD Deployment Jobs window that you can access from Deploy mode of Service View by selecting View Deployment Jobs from the task pane, click the job ID of the assignment job.

   The Job Management page shows the progress and status of the role assignment job.

6. To verify the result, in Build mode, select Prestage Devices > Manage Device Roles from the tasks pane.

   The Manage Device Roles window shows two devices that can be used for provisioning.

7. To unassign a device from N-PE role assignment, click Manage Device Roles and from the drop-down list, select Unassign Role to remove the role capability of a network element. You are prompted to confirm the operation. If you click OK, a request is submitted to remove the latest role of the network element or device.

Choosing or Creating a Service Definition

A service definition provides a template upon which services are built. It specifies service attributes that are not specific to a service instance. In our example, the service definition provides all service attributes except the N-PE devices, the UNIs, and bandwidth.

The Network Services application ships with standard service definitions. First, we check the standard service definitions to determine whether one already exists that will work.

1. From the View selector, select Service View. The workspaces that are applicable to routing and tunnel services are displayed.
2. Click the Build icon in the Service View of the Connectivity Services Director banner. The functionalities that you can configure in this mode are displayed in the task pane.
3. In the Network Services > Connectivity task pane, select Service Design > Manage Service Definitions.

   The Manage Service Definitions page lists all service definitions in the system. In a new system, the screen lists only predefined service definitions.

   This example requires a service definition with UNIs that use 802.1Q interfaces and allow you to set a bandwidth of 25 Mbps. The standard service definitions have several examples for provisioning 802.1Q UNIs, but none that allow the setting of a 25 Mbps bandwidth limit. You need to create a new service definition.

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

   The General window appears.

5. Enter a name for the service definition. For this example, enter p2p-dot1q-sd-1.
   
   
6. Click Next.

   The UNI Settings window appears.

7. In the Connectivity Settings window, to pick the default connectivity settings, click Next.
8. In the UNI Settings window, in the Ethernet option field, select dot1q.
9. In the Customer traffic type field, select Transport single VLAN.
10. In the VLAN ID selection field, select Select manually.
11. In the VLAN range for manual input field, specify the range.
12. In the Outer Tag protocol ID field, select 0x88a8
13. In the Physical IF encapsulation field, select flexible-ethernet-services.
14. In the Logical IF encapsulation field, select vlan-ccc.
15. In the Bandwidth Settings panel, select the Enable rate limiting check box.
16. In the Default Bandwidth field, enter 10, for a default bandwidth of 10 Mbps.
17. To the right of the value you just entered, select the Editable in service order check box.

    The Min Bandwidth (Kbps), Max Bandwidth (Mbps), and Increment (Kbps) become active.

18. In the Min Bandwidth (Kbps) field, enter 100.
19. In the Max Bandwidth (Mbps) field, enter 10000.
20. In the increment field, enter 64.

    These settings of the Bandwidth range and Increment fields allow the bandwidth to be set in the service to any 64-Kbps increment in the range of 100 Kbps through 10000 Mbps.

21. To save and complete the service definition, click Finish.

    The Manage Service Definitions page includes the new service definition.

    You have created a customized Service Definition, but it has not yet been published. Before a service definition can be used in provisioning, it must be published.

22. To publish the service definition, in the Manage Service Definitions page, select the p2p-dot1q-sd-1 service definition; click the Publish Service Definition button.

    The Publish Service Definition window appears.

23. To confirm that you want to publish this service definition, click Publish.

    In the Manage Service Definitions page, the symbol in the upper left corner of the service definition changes to a check mark, indicating that the status has changed to Published.

The service definition is now ready for use in provisioning.

Creating a Customer

Before you can provision the service, customer details must be present in the Junos Space database. To add a customer:

1. From the View selector, select Service View. The workspaces that are applicable to routing and tunnel services are displayed.
