Abstract
Grouping pseudowires based on hardware interfaces and configured control paths enables improved pseudowire failover performance. Signaling status changes (e.g., from standby to active status) is facilitated by using group IDs for the pseudowire groups, thereby enabling improved failover performance when there is disruption in the network.
