Configuring Pseudowire Redundancy
Pseudowire (PW) Redundancy enables you to configure a backup pseudowire in case the primary
pseudowire fails. When the primary pseudowire fails, the PE router can switch to the backup pseudowire.
Traffic can be switched back to the primary pseudowire after the path is operational again.
You can configure the network with redundant pseudowires and redundant network elements, as shown
in Figure 15-1.
