Abstract
A method and apparatus that proxies connectivity check messages and sends fault state changes messages across an MPLS/VPLS network is described. A network element proxies connectivity check messages for remote maintenance endpoints based on a local database. The network element updates the database based on received fault state change message that identify a fault state change of a remote maintenance endpoint. The network element detects fault state changes of local maintenance endpoints and sends a fault state change message to other network elements that proxy connectivity check message for the local maintenance endpoints.
