Abstract
Providing protection to network data traffic over Pseudowires includes sending a Pseudowire TLV containing a precedence parameter to each of a set redundant Pseudowires between provider edge nodes. In the event that the designated active Pseudowire of a set of Pseudowires becomes unavailable, this configuration parameter allows peer provider edge nodes to be notified of the precedence of each Pseudowire in the redundant set in order to coordinate a switchover operation to a preferred protection Pseudowire.
