End Host and Subnet Route Distribution
Forwarding between servers within a Layer-2 VNI
Figure 10: Packet Forwarding (Bridge)
The VNI of the source end host, Host A, and the target end host, Host B, is 30000.
• Host A sends traffic to the directly attached VTEP V1.
• V1 performs a lookup based on the destination MAC address in the packet header (For communication
that is bridged, the target end host's MAC address is updated in the DMAC field).
• VTEP V1 bridges the packets and sends it toward VTEP V2 with a VXLAN header stamped with the
Layer 2 VNI 30000.
• VTEP V2 receives the packets, and post decapsulation, lookup, bridges them to Host B.
