In VXLAN, what does the destination MAC in the outer Ethernet header identify?

In VXLAN, the outer Ethernet header encapsulates the original Ethernet frame. The destination MAC address in this outer header identifies the MAC address of the next hop device that will forward the VXLAN-encapsulated packet towards its final destination. This is typically the MAC address of the VTEP (VXLAN Tunnel Endpoint) on the remote leaf switch if the two VTEPs are directly connected, or the MAC address of an intermediate router if they are not. "The leaf switch" is too general; it's specifically the next hop to the leaf switch. "The remote switch" is also too general; it's the next hop towards the remote switch. "The remote spine" is incorrect as spine switches typically operate at Layer 3 and do not terminate VXLAN tunnels; they route the encapsulated packets.
