Design FRR Backup Tunnels Window

 

In the Juniper NorthStar Planner main window, select Application > FRR Design. The Design FRR Backup Tunnels window is displayed and if this is the first time FRR Design is selected, you are prompted to perform an FRR Auto Design as shown in Figure 1.

Figure 1: Design FRR Backup Tunnels Window
Design FRR Backup Tunnels Window

To evaluate the existing backup design, select a tunnel and click Evaluate. You are prompted to select the diversity level and click OK. You are prompted to display the design report.

To display the paths of the backup tunnel, protected segment, and protected tunnels in the center pane of the topology map window and in a separate Paths window, select a tunnel and click Show Paths. The paths are highlighted and animated in the topology map window.

To display the selected tunnel in the Network Info window, click View Path Details.

To display the tunnels that are protected by the Backup Tunnel created using the FRR Design wizard, select the Backup Tunnel entry in the Design FRR Backup Tunnels window and click View Protected Tunnels.

To save the design report as a CSV file, click Report.

To delete the selected tunnels or all tunnels, select Delete > Selected or Delete > All Entries.

To create a design, select Design > Selected or Design > All Entries. The Design Options window is displayed as shown in Figure 2.

Table 1 lists the basic design options available.

Table 1: Design Options Window Basic Options Tab for FRR Backup Tunnels

Option

Description

Backup Tunnel Design Mode

Select whether to modify the tunnels using the parameters listed in this table or to create tunnels using the selected tunnels as a template.

Diversity Level

Indicates whether the backup tunnel has a route that is Link-Diverse, Site-Diverse, or Facility-Diverse from the protected path.

Design Bandwidth

The amount of bandwidth the newly created backup tunnel can protect. The following choices are available:

  • Select Link Bandwidth and set the bandwidth as a percent of the link bandwidth in the Set Design Bandwidth to % field.

  • Select Sub-Pool Bandwidth and set the bandwidth as a percent of the sub-pool bandwidth in the Set Design Bandwidth to % field.

  • Select Sum of FRR Primary Tunnel Bandwidth and do not set a percent value.

Note: The Design Bandwidth is used for Design purposes only, to decide where to place the tunnel, and is not used to set the actual RSVP bandwidth.

Fixed Bandwidth amount to add to Design Bandwidth

Specify a fixed amount of bandwidth to add to the Design Bandwidth for the backup tunnel.

Set RSVP Bandwidth to % of the Design Bandwidth

Specify the actual bandwidth to use for the backup tunnel, as a percentage of the Design Bandwidth.

Incremental: Paths that already have explicit routes are not recalculated.

Select to exclude paths that already have explicit routes.

Redesign: Paths that already have explicit routes are recalculated

Select to include paths that already have explicit routes.

Table 2 lists the advanced design options available from the Advanced Options tab.

Table 2: Design Options Window Advanced Options Tab for FRR Backup Tunnels

Option

Description

Number of generated FRR tunnels determined by:

  • Maximum bandwidth per tunnel

  • Number of tunnels per interface

This is the maximum bandwidth allowed for the backup tunnel. If the Design Bandwidth exceeds this value, then multiple backup tunnels will be created.

Prompt to view FRR design report

By default you are prompted to view the report when the design is complete. You can disable this feature by clearing this option.

Automatically delete failed FRR backup Tunnels

By default failed FRR tunnels are not deleted. You can set the system to delete the tunnels by selecting this option.

Mark new paths as configured

By default new paths are marked as Required. You can disable this feature by clearing this option.

After you create a design, the design report is displayed in the Report Viewer window.

In the Report Viewer window, you have the table sorting capabilities as described in File Manager Report Viewer Window.
