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 set of 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.

Steps

Perform How do I create a tunnel template?.

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.

Configure the parameters, as required:

Parameter	Description
Source NE ID	Specifies the identifier of the source NE
SDP ID	Specifies the SDP IP
Name	Specifies the name of the tunnel
Destination NE ID	Specifies the identifier of the destination NE
Description	Describes the tunnel
Admin State	Specifies the initial administrative state of the tunnel upon deployment
Transport Type	Specifies the type of transport to be used by the tunnel, MPLS or GRE
Signaling	Specifies the signaling method to be used by the tunnel
MTU	Specifies the MTU of the tunnel
Metric	Specifies the metric of the tunnel

If the Transport Type parameter was set to MPLS, configure the required parameters:

Parameter	Description
Mixed LSP Mode	Specifies whether mixed LSP mode is enabled for the tunnel
Revert Time	Specifies the revert time, when mixed LSP mode is enabled
Enable LDP	Specifies whether LDP is enabled for the tunnel
Enable BGP Tunnel	Specifies whether BGP tunnel is enabled for the tunnel
SR-ISIS	Specifies whether SR-ISIS is enabled for the tunnel
SR-OSPF	Specifies whether SR-OSPF is enabled for the tunnel
LSP	Specifies the LSP to be associated with the tunnel

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

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.

Configure the required parameters:

Parameter	Description
Steering Parameters	Specifies the steering parameter(s) to be associated with the tunnel
Tunnel Admin Group	Specifies the administrative group to which the tunnel will belong

Perform one of the following:

Select the Reserve Resources check box and click PLAN to create the tunnel in a Planned state.
Click SAVE to create the tunnel in a Saved state.
Click DEPLOY to create the tunnel in a Deployed state.
