Remote MAC addresses can be learned by the VTEP only through data flooding.

Although the static VXLAN tunnel mode supports the distributed gateway scenario, the configuration involves a heavy workload and is complex to adjust.

A static VXLAN tunnel also uses corresponding protocols on the control plane, which consumes device resources.

If N devices need to establish static VXLAN tunnels, a maximum of N(N - 1)/2 tunnels need to be manually configured, which involves a heavy workload.
