What two concisions can you draw from the corresponding FortiGate configuration? (Choose two.)
A . IPSec Tunnel aggregation is configured
B . net-device is enabled in the tunnel IPSec phase 1 configuration
C . OSPI is configured to run over IPSec.
D . add-route is disabled in the tunnel IPSec phase 1 configuration.

Answer: B, D

Explanation:

Option B is correct because the routing table shows that the tunnel interfaces have a netmask of 255.255.255.255, which indicates that net-device is enabled in the phase 1 configuration. This option allows the FortiGate to use the tunnel interface as a next-hop for routing, without adding a route to the phase 2 destination1.

Option D is correct because the routing table does not show any routes to the phase 2 destination networks, which indicates that add-route is disabled in the phase 1 configuration. This option controls whether the FortiGate adds a static route to the phase 2 destination network using the tunnel interface as the gateway2.

Option A is incorrect because IPSec tunnel aggregation is a feature that allows multiple phase 2 selectors to share a single phase 1 tunnel, reducing the number of tunnels and improving performance3. This feature is not related to the routing table or the phase 1 configuration.

Option C is incorrect because OSPF is a dynamic routing protocol that can run over IPSec tunnels, but it requires additional configuration on the FortiGate and the peer device4. This option is not related to the routing table or the phase 1 configuration.
