Abstract
A method and system for sharing host entries between virtual tunnel endpoints (VTEPs). The method includes making a first determination that an NLHE is present in a locally learned host entry table on a VTEP where the NHLE is associated with a first timestamp, and making a second determination that a first entry corresponding to the NHLE is present in a Host-Specific Portion of Global Host Entry Table (HSPT) on the VTEP, where the first entry is associated with a second timestamp. Based on the second determination, making a third determination, using the timestamps, that the NHLE is more recent than the first entry and based on the third determination updating an active forwarding table on the first VTEP to include a second entry corresponding to the NHLE and to remove the first entry and sending the NHLE to a VXLAN controller operatively connected to the VTEP.
