How do I create a service tunnel?

Purpose

Use this procedure to create a new service tunnel. Brownfield service tunnels, created previously in NFM-P or on MDM-managed nodes, can be discovered by NSP and used by services, but their properties cannot be modified from the NSP's service management views. They can, however, have steering parameters applied to them, and have workflows executed on them.

The parameters that are available to you during service tunnel creation is dependant on the intent type that is associated with the tunnel template you select, and may differ from those described in this procedure, which assumes the Nokia-provided tunnel template is being used.

Perform How do I create a service template?.

2 

Perform one of the following:

    1. From the Service Management, Service Tunnels view, click + CREATE.

      The Select a tunnel template to start form opens displaying a list of tunnel templates.

    2. Click on a tunnel template from the list.

      The Create Tunnel form opens with the Template Name parameter populated.

    1. During service creation, click on the SDP ID field, then click + CREATE TUNNEL.

      The Create Tunnel form opens.

    2. Click on the Template Name field and select a tunnel template from the list.

LSP

Specifies the LSP to be associated with the tunnel

5 

Configure the required Hello parameters:

Parameter

Description

Keep Alive Enabled

Specifies whether keep alive is enabled for the tunnel

Hello Time

Specifies the hello time of the tunnel

Hello Message Length

Specifies the hello message length of the tunnel

Hello Request Timeout

Specifies the hello request timeout of the tunnel

Hold Down Time

Specifies the hello down time of the tunnel

Max Drop Count

Specifies the maximum drop count of the tunnel

6 

If the Transport Type parameters was set to GRE, configure the Allow Fragmentation parameter (if required), which specifies whether or not fragmentation will be allowed for the tunnel.

7 

Configure the required parameters:

Parameter

Description

Steering Parameters

Specifies the steering parameter(s) to be associated with the tunnel
