Dear friend!
Static Tunnel: The manually created tunnels are called Static Tunnels.
Dynamic Tunnel: The tunnels that are auto-discovered are known as dynamic tunnels.
Comparison between dynamic tunnels and static tunnels: Dynamic tunnels are better than static tunnels in tunnel deployment and capacity expansion. Static tunnels have outstanding advantages in terms of network scale and reliability and maintainability during long-term network operation. Therefore, it is strongly recommended that the static deployment mode be used. For sites where the dynamic deployment mode is required, exercise caution when designing the network.
Thank you!
