NVGRE and VXLAN Encapsulation Extension for L3 Overlay
Xiaohu Xu, Lucy Yong · 2013
Both NVGRE and VXLAN encapsulations were originally designed for L2 overlay only. This draft proposes the enhancement on both to support L3 overlay as well. The proposed method completely decouples the L3 overlay from the L2 overlay in terms of encoding schema and data processing.
