DA: Indicates the outer destination MAC address. Unicast is the MAC address of the next hop router, and multicast replication is the multicast MAC address.

SA: Indicates the outer source MAC address, which is the MAC address of each hop router.

DIP: indicates the IP address of the destination NVE.

 SIP: Indicates the IP address of the source NVE.

UDP Dest Port: VXLAN reserved UDP destination port number. The default value is 4789.

UDP Source Port: The value is dynamically generated based on the hash value of the data flow.

VxLAN I flag: This parameter must be set to 1, indicating that the VNI field is valid.

VxLAN VNI: 24 bits, used to identify a virtual network. A maximum of 16 Mbit/s is supported.

Original Ethernet Frame: According to the standard, after VXLAN encapsulation is performed on packets, the VLAN tag of the original packets needs to be removed. Even if the packets are not stripped, the packets are forwarded based on the VNI in the egress NVE (the VLAN of the original packets is ignored).
