Optimizing Tunnel Paths Overview

The Optimizing Tunnel Paths chapter describes how to optimize your tunnel paths using the net grooming feature.

Use this chapter to learn how to improve the routing of tunnels in your network.

If you wish to perform this task in the NorthStar Planner client, you should have already added tunnels to your network. You may use 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.

Before using the network grooming feature, you must change the tunnel path settings from “required” to “preferred” for the paths whose routes you want to improve. You change the tunnel path settings manually by changing the Path Required PR (path) statements to Path Select PS (path) statements in the tunnel file.
