Tunnel Path Design Overview


This chapter describes the Path Design feature. Tunnel Path Design lets you design tunnel paths for path diversity. Lsp tunnels can be designed such that their secondary/standby paths are routed in node-diverse, site-diverse, link-diverse, or facility-diverse routes from their primary path. Additionally, two different tunnels can also be designed such that their primary paths are also on diverse paths.


A license for tunnels is required for this feature. Please contact your Juniper representative for more information.

Use these procedures to design primary and backup tunnel paths.

If you wish to perform this task in IP/MPLSView, you should have already added tunnels to your network.You may wish to follow along by using the spec.mpls-fish specification file located in your $WANDL_HOME/sample/IP/fish directory (where $WANDL_HOME is /u/wandl by default).

For instructions on how to view or modify the tunnels in your network, see IP/MPLSView LSP Tunnels Overview.

For information on the meaning of the tunnel type fields, refer to the “tunnelfile” entry in the “Demand/Traffic Files” chapter of the File Format Reference for IP/MPLSView.
