Summary:Systems, methods, and computer-readable media for OAM in overlay networks. In response to receiving a packet associated with an OAM operation from a device in an overlay network, the system generates an OAM packet. The system can be coupled with the overlay network and can include a tunnel endpoint interface associated with an underlay address and a virtual interface associated with an overlay address. The overlay address can be an anycast address assigned to the system and another device in the overlay network. Next, the system determines that a destination address associated with the packet is not reachable through the virtual interface, the destination address corresponding to a destination node in the overlay network. The system also determines that the destination address is reachable through the tunnel endpoint interface. The system then provides the underlay address associated with the tunnel endpoint interface as a source address in the OAM packet.
