SteelHead™ Deployment Guide : Path Selection
  
Path Selection
This chapter describes path selection. Path selection is available in RiOS v8.5 or later. Path selection enables the SteelHead to redirect traffic to a predefined available WAN path for a given application in real-time, based on path availability. This chapter includes the following sections:
  • Overview of Path Selection
  • Path Selection Implementation
  • Configuring Path Selection
  • Valid Path Selection Deployment Design Examples
  • Path Selection and Virtual In-Path Deployment
  • Design Validation
  • Design Considerations
    • To avoid repetitive configuration steps on single SteelHeads, Riverbed strongly recommends that you use the SCC v9.0 or later to configure path selection on your SteelHeads. SCC enables you to configure one time and to send it out to multiple SteelHeads instead of connecting to a SteelHead, performing the configuration, and repeating the same configuration for all SteelHeads in the network.
    For more information about path selection, including configuration, see the SteelHead Management Console User’s Guide and the Riverbed Command-Line Interface Reference Manual.
    This chapter requires you be familiar with Topology and Application Definitions.
    If you are using a release previous to RiOS v9.0, the features described in the chapter are not applicable. For information about applications before RiOS v9.0, see earlier versions of the SteelHead Deployment Guide on the Riverbed Support site at https://support.riverbed.com.
