Techniques are provided to support an extension to PFM-SD that avoids multicast traffic flooding across multi-home provide edge nodes, and maintains a faster convergence capability provided by multi-homing. These techniques allow a last hop router to create two trees, and provides a framework to ensure that Ethernet Segment failure has minimum traffic close for a receiver. In addition, these techniques involve a mechanism to avoid traffic flood over a core network between peers.
