2. Specify a filter for the search, if required, and click on the Search button. A list of routers appears.

3. Choose an entry and click on the OK button. The Select Destination System IP / Router - IGP- SIMULATION form closes.

4. Click on the Select button next to the Destination IP Address parameter. The Select Destination IP Address - IGP- SIMULATION form opens.

5. Specify a filter for the search, if required, and click on the Search button. A list of routers appears.

6. Choose an entry and click on the OK button. The Select Destination IP Address - IGP- SIMULATION form closes.

Configure the Administrative State parameter.

Click on the Properties tab button.

Configure the parameters:

• Enable CSPF

• Enable TE Metric

• Reserved Bandwidth

• Hop Limit

• ECMP Tie Breaker

• Measured Bandwidth

The Measured Bandwidth parameter is auto-populated when your scenario uses imported LSPs that are enabled for statistics collection.

Click on the Administrative Groups tab button.

Choose one or more administrative groups from the Unassigned list in the Included Groups panel and click on the right arrow button. The administrative group or groups move to the Assigned list.

Note: The links in the calculated CSPF must include the specified administrative groups.

Choose one or more administrative groups from the Unassigned list in the Excluded Groups panel and click on the right arrow button. The administrative group or groups move to the Assigned list.

Note: The links in the calculated CSPF must exclude the specified administrative groups.

Create one or more LSP paths.

1. Click on the LSP Paths tab button.

2. Click on the Create LSP Path button. The Simulated LSP Path SIMULATION (Create) form opens with the General tab displayed.

3. Configure the parameters:

   • Name

   • Description

   • Type

   • Standby

   The Standby parameter is configurable when the Type parameter is set to secondary.

4. Click on the Select button next to the Path ID parameter. The Select Provisioned MPLS Path - Simulated LSP Path - MPLS - SIMULATION form opens with a list of provisioned paths.

5. Choose an entry and click on the OK button. The Select Provisioned MPLS Path - Simulated LSP Path - MPLS - SIMULATION form closes.

6. Configure the Administrative State parameter.

7. Click on the Properties tab button.

8. Configure the parameters:

   • Reserved Bandwidth

   • Hop Limit

   • Admin Groups Included

   • Admin Groups Excluded

   • ECMP Tie Breaker

   You can specify that the parameter value is inherited from the LSP configuration using the Inherit Value parameter.

9. Click on the Administrative Groups tab button.

10. Choose one or more administrative groups from the Unassigned list in the Included Groups panel and click on the right arrow button. The administrative group or groups move to the Assigned list.

    Note:

    The links in the calculated CSPF must include the specified administrative groups.

11. Choose one or more administrative groups from the Unassigned list in the Excluded Groups panel and click on the right arrow button. The administrative group or groups move to the Assigned list.

    Note:

    The links in the calculated CSPF must exclude the specified administrative groups.

12. Click on the following tab buttons to view information.

    • Provisioned Path

    • Actual Path—the actual path is available only after the impact analysis if the LSP path is operationally up.

13. Click on the Apply button.

14. Click on the Path Records tab button.

15. Click on the Search button. A list of LSP path records appears.

16. Choose an entry and click on the Properties button. The LSP Path Record SIMULATION (Edit) form opens with the General tab displayed.

17. Click on the following tab buttons to view information.

    • Scenario

    • Segments

18. Close the LSP Path Record SIMULATION (Edit) form.

Click on the OK button. The Simulated LSP Path SIMULATION (Edit) form closes.

Click on the Impact Analysis button on the SIMULATION - Protocol Model - Scenario topology map to converge the topology. The Legend - SIMULATION - Protocol Model - Scenario form opens with the Last Impact Results tab displayed.

Note: For quick reference to the last results of the impact analysis, you can keep the Legend - SIMULATION - Protocol Model - Scenario form open while you are working with the simulation topology.

Click on the View Impact Details button, if required, to view the details of the impact analysis. The Action Event - Impact Analysis - SIMULATION - Scenario (Edit) form opens with the General tab displayed.

Click on the following tab buttons to view information about the impact analysis:
