Perform To open a scenario to open a simulation topology map.

Note: You can only create a CSPF highlight request if the topology is converged. The grey operational mode indicator at the top-left of the topology map must be Topology converged. If the operational indicator is yellow, click on the Impact Analysis button. The Legend - SIMULATION - IGP Model - Scenario form opens with the Last Impact Results tab displayed. Click on the Close button.

Perform one of the following:

1. Right-click on the map and choose Highlight IGP Links→Highlight from the contextual menu. The Highlight CSPF Request form opens with the General tab displayed.

2. Perform the following:

   1. Press the Ctrl key and click on a source and destination router or link.

   2. Right-click on a router and choose Highlight CSPF from the contextual menu. The Highlight CSPF Request form opens with the General tab displayed.

Configure the parameters:

• Protocol

• Required Bandwidth

• Hop Limit

• System Instance ID

Click on the Select button next to the Source IP parameter. The Select Source Router form opens.

Note: If you performed Step 2 b , the Source IP parameter is already configured with the source router IP address.

Specify a filter and click on the Search button. A list of simulated routers appears.

Choose an entry and click on the OK button. The Select Source Router form closes and the Highlight CSPF Request form reappears with the source router information.

Click on the Select button next to the Destination FEC parameter. The Select Destination FEC form opens.

Note: If you performed Step 2 b , the Destination FEC parameter is already configured with the destination router IP address.

Specify a filter and click on the Search button. A list of simulated routers appears.

Choose an entry and click on the OK button. The Select Destination FEC form closes and the Highlight CSPF Request form reappears with the destination information.

Click on the Admin Groups tab button.

Choose an administrative group from the Unassigned list in the Included Groups panel and click on the right arrow button. The administrative group moves to the Assigned list.

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

Choose an administrative group from the Unassigned list in the Excluded Groups panel and click on the right arrow button. The administrative group moves to the Assigned list.

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

Click on the Excluded Routers tab button.

Specify the routers that are to be excluded from the CSPF highlight. The highlighted CSPF must not pass through the routers with the specified router IDs. Perform the following:

1. Click on the Add button. The Select Excluded Routers form opens.

2. Specify a filter and click on the Search button. A list of simulated routers appears.

3. Choose one or more routers and click on the OK button. The Select Excluded Routers form closes.

Click on the Excluded Egress IP Addresses tab button.

Specify the egress IP addresses that are to be excluded from the CSPF highlight. The highlighted CSPF must not pass through the egress interfaces with the specified IP addresses.

1. Click on the Add button. The Select Excluded Egress IP Links form opens.

2. Select an icon from the top-left panel.

3. Specify a filter and click on the Search button.

4. Choose one or more links and click on the OK button. The Select Excluded Egress IP Links form closes.

Click on the OK button. The Highlight CSPF Request form closes and the CSPF is highlighted on the topology map.

To remove the CSPF highlight, click on the Legend button and choose Highlight Sessions from the contextual menu. The Legend - SIMULATION - IGP Model form opens with the Highlight Sessions tab displayed

Disable the checkboxes of the highlights you want to remove from the topology map. You can click on the Clear All button to disable all of the checkboxes.

Click on the Apply button. The selected highlights are removed from the topology map.

Click on the Close button. The Legend - SIMULATION - IGP Model form closes.
