1. A method comprising:

  • assigning a discriminator to a target in communication with a reflector at a network device, the target comprising a plurality of entities monitored by the reflector;

    identifying at the reflector, a packet comprising the assigned discriminator, the packet transmitted from a seamless bidirectional forwarding detection (S-BFD) initiator node in an S-BFD session with the reflector node to test said plurality of entities; and

    transmitting a response packet from the reflector to the initiator in response to receiving the identified packet, the response packet comprising information for the target obtained by the reflector through monitoring of the target to provide a status of said plurality of entities to the S-BFD initiator node;

    wherein the discriminator comprises an aggregate discriminator and each of said entities is assigned an S-BFD discriminator and wherein S-BFD is stateless on the target.
