Techniques are provided for detecting connectivity failures within an OTV network using CFM. In an embodiment, a method and apparatus for using E-OAM to accurately test connectivity in an OTV network is provided. In an embodiment, one method comprises: in a first edge router that is in a local area network (LAN) and that is coupled to a core network: maintaining, for each node of the LAN, a mapping of a source address to one or more delivery multicast groups, each delivery multicast group comprising a set of other edge routers, each of the other edge routers having a connection to a distinct LAN; receiving a frame from a particular source node of a particular source address; sending the frame to a plurality of the delivery multicast groups that are mapped, in the mapping, to the particular source address. |
