ABSTRACT:
A network device may include logic to establish an IP session, establish a BFD session within the established IP session, transmit BFD packets within the established BFD session, and determine that the established IP session is active based upon reception of the BFD packets. In another embodiment, the logic may also determine that an IP session is active using an inactivity timer that may also trigger transmission of BFD packets.
