IPsec tunnel mode protection only provides protection over part of the route, while transport mode protection provides protection for the entire route. This is because in tunnel mode, the original IP packet is encapsulated within a new IP packet, and the original packet header is hidden within the new packet. This means that protection is only provided for the portion of the route between the two endpoints of the tunnel, not the entire path. Additionally, tunnel mode may incur higher costs due to the need for additional processing and overhead associated with encapsulation.
