摘要:
The protection of multi-segment pseudowires by utilizing backup paths is disclosed herein. Disclosed embodiments include methods that establish at least one backup path for multi-segment pseudowires, the establishing being performed prior to detection of failure in the primary path. Upon detecting a path failure, the detected failure is signaled to the head-end, a backup path is chosen, and reachability information associated with the chosen backup path is signaled across the backup path before reverse traffic is switched to the backup path. In other disclosed embodiments, apparatus are configured to establish, prior to detection of failure in the primary path, at least one backup path for the multi-segment pseudowire.
