Tunnel Services Overview
Transport or tunnel services allow you to design, provision, and deploy label-switched path (LSP) services that run from a specific ingress router to a specific egress router. You can configure end-to-end point-to-point and point-to-multiple-point LSPs.
A tunnel service automates and provides a user interface for LSP service deployment, including LSP-configured Juniper Networks device discovery from the Junos Space Platform database, LSP definition configuration design, and LSP service validation and deployment.
A tunnel service is integrated with and codependent upon network services, that provide Layer 2 and Layer 3 VPN service provisioning.
Provisioning an LSP service includes the following major tasks:
Discover Juniper Networks devices that have been configured for MPLS-Signaled LSP into Junos Space using the Devices workspace. See the MPLS-Signaled LSP Configuration Guidelines in the Junos OS MPLS Applications Configuration Guide.
Discover tunneling or transport devices from the Connectivity Services Director GUI in Service View of Build mode. In the Network Services > Connectivity task pane, select Prestage Devices > Prestage Devices. View the values displayed under the Roles column of the discovered devices.
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.
Assign LSP roles to provide authorization for the LSP definition designer and service activator to provision LSP services. Select Platform > Users.
Create an LSP definition to use to create an LSP service. Select TA Design> Manage TA Definitions.
Create and validate LSP services. Select Service Provisioning> Manage LSPs. You can use LSP settings in the predefined LSP definition so that they are configurable in the LSP service order.
