What is true regarding the static route configuration for IPsec?

The configuration for static routes in the context of IPsec involves several considerations, particularly about how IPsec interfaces operate. The accurate statement is that a gateway address is not needed because the interface is point-to-point.

IPsec tunnels create a virtual point-to-point link between two endpoints. This means that the traffic routed through an IPsec tunnel directly communicates with the remote device at the opposite end of the tunnel without needing an additional hop to a gateway. Unlike traditional routed interfaces, which might require a gateway to determine the next hop for outbound traffic, IPsec interfaces effectively treat the remote end as if it were directly attached.

In this scenario, the dynamic nature of establishing secure tunnels allows for traffic to be sent directly over the IPsec interface without the necessity for a separate gateway, simplifying the routing process for traffic destined for the opposite end of the VPN tunnel. Thus, understanding the point-to-point nature of IPsec interfaces is crucial to grasping why gateway addresses are not required in this specific configuration.

Other options may suggest different requirements or capabilities regarding the configuration of IPsec static routes, but they do not accurately reflect the operational characteristics of point-to-point links in IPsec scenarios.
