Tunnel Path Extraction
The tunnel path extraction feature shows the exact network view of tunnel paths. It helps to simulate the impact of tunnel set up on IGP routing by taking into account Explicit Tunnel Routing, Affinity and Trunk attributes. This is useful if the LSPs can be dynamic (as opposed to explicit). IP/MPLSView displays the current status and routing of the LSP tunnels within the defined network.
 | Note: The tunnel path feature requires a license. Please contact your Juniper Networks representative for more details on this feature. |
The MPLS Tunnel Extraction feature retrieves the actual placement of the tunnel and the status (up or down) of the LSP paths by parsing the output of the following Juniper Networks Junos OS command:
show mpls lsp statistics extensiveThe same is true for the following Cisco IOS command:
show mpls traffic-eng tunnelsTo use this feature, you must have a network open and then specify a directory that contains the output of these commands. There should be one file per router. On the second page of the Import Wizard, select Tunnel Path in the Import Type selection box. Then click on the Browse button above to open the Import Directory Chooser window.
Navigate to the directory that contains the files and press Select. Click.Next > to continue.
This should generate an IP/MPLSView format file of the tunnel paths and status called tunnelpath.runcode, where runcode is the file extension used for your network model. This will automatically be loaded into the network model.
