Abstract
A system and method for detecting a communication status includes generating, at an originating virtual tunnel end point (VTEP), a network virtualization using generic routing encapsulation (NVGRE) data packet in accordance with NVGRE protocols. A bidirectional forwarding detection (BFD) data packet is encapsulated in the NVGRE data packet to provide an NVGRE BFD data packet. The NVGRE BFD data packet is transmitted to a terminating VTEP to establish a BFD session over an NVGRE tunnel. A communication status of the NVGRE tunnel is determined for the BFD session based on a reply BFD data packet received from the terminating VTEP in accordance with a receiving time interval.
