摘要:
A method and system for redundancy in Ethernet Virtual Connections (EVCs) are disclosed. In one embodiment, a method includes transmitting continuity check messages from a node in an Ethernet Virtual Connection connecting at least one root node and a plurality of leaf nodes in a point-to-multipoint or multipoint-to-multipoint connection, identifying a failure in a primary path between the root node and the leaf nodes, switching to a backup path, and advertising the switching to the backup path to at least one node.
