A system and method are provided for faster convergence with multihoming using internet protocol (IP) performance measurement (PM) sessions to report, to a transmitting provider edge (PE), a state of health of a connection between a multihomed node and a receiving (PE). The state of health can be the liveness of the connection. The receiving PE locally monitors the state of health of its connection to the node, and encodes information of the state of health in a field of the PM session messages sent to the transmitting PE. For example, while the PM session messages indicate the connection is live, traffic from the transmitting PE to the node is routed through the receiving PE. Upon the PM session messages indicating the connection is no longer live, the transmitting PE instead routes traffic to the node through another receiving PE with which the node is multihomed.
