▄ Cisco ASR 903 Router Design and Deployment Guide
As shown in figure above, one pseudowire transports data between the U-PE router and its peer N-PE routers.
When a failure occurs along the path of the U-PE router, the backup pseudowire and the redundant N-PE router
become active and start transporting data.
