Static VXLAN (Unicast VXLAN)

You can implement Virtual Extensible LAN (VXLAN) in a small multichassis link aggregation group (MC-LAG) network using the static VXLAN feature. In the MC-LAG network, Juniper Networks devices function as source and destination virtual tunnel endpoints (VTEPs). In this environment, static VXLAN serves two purposes: 

•  To learn the MAC addresses of hosts in a VXLAN. 
• To encapsulate Layer 2 packets with a VXLAN header and later de-encapsulate the packets, thereby enabling them to be tunneled through an underlying Layer 3 IP network.
