VXLAN Unicast Configuration
This chapter contains basic Static-VXLAN unicast configuration examples.
Port Mapping
In this example each VTEP (VTEP1 and VTEP2) is a multilayer switch where xe2 is an access port while xe1 is network port.
After we start sending a packet (say untagged ipv4 packet) from VM1, it hits the VTEP1,VTEP1 does encapsulation based on the VNID configured and send it on xe1. Now the packet reaches VTEP2 and it does decapsulation of the packet. Now based on VNID packet is sent out on access port and it reaches destination VM, VM2.
Topology
The procedures in this section use the topology in Figure 2-2

Intermediate Non-VXLAN Router
This example is same as port mapping but we have an intermediate non VXLAN router. It does forwarding based on IP header.
