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.

Use these procedures to design primary and backup tunnel paths.

If you wish to perform this task in NorthStar Planner, 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 NorthStar Planner LSP Tunnels Overview.
