Configuring the Soft PVP or Soft PVC Route Optimization Feature

This section describes the soft PVP or soft PVC route optimization feature. Most soft PVPs or soft PVCs
have a much longer lifetime than SVCs. The route chosen during the soft connection setup remains the
same even though the network topology might change.
Soft connections, with the route optimization percentage threshold set, provide the following features:
•
•
Soft PVC route optimization should not be configured with constant bit rate (CBR) connections.
Note
Route optimization is directly related to administrative weight, which is similar to hop count. For a
description of administrative weight, see
Configuring soft PVP or soft PVC route optimization is described in the following sections:
•
•
For overview information about the route optimization feature refer to the Guide to ATM Technology.

Enabling Soft PVP or Soft PVC Route Optimization

Soft PVP or soft PVC route optimization must be enabled and a threshold level configured to determine
the point when a better route is identified and the old route is reconfigured.
To enable and configure route optimization, use the following global configuration command:
Command
atm route-optimization
percentage-threshold percent
Example
The following example enables route optimization and sets the threshold percentage to 85 percent:
Switch(config)# atm route-optimization percentage-threshold 85

When a better route is available, soft PVPs or PVCs are dynamically rerouted
Route optimization can be triggered manually
