Abstract
Methods and apparatuses for determining an NVGRE data path failure are provided. In an embodiment, a first data packet comprising an echo request is generated at an originating tunnel end point device in a network. The echo request includes an NVGRE network identifier (VSID) associated with a selected NVGRE segment. A second data packet is generated comprising a header having a format associated with an NVGRE technology, the header comprising a network identifier portion including the NVGRE network identifier (VSID). The first data packet is encapsulated in the second data packet, and the second data packet is transmitted via the selected NVGRE segment.
