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.Reference: =

The Virtual Router Redundancy Protocol (VRRP) configuration in the exhibit indicates that 10.1.5.254 is set as the virtual IP (VRIP), commonly serving as the default gateway for the internal network (A). With vrrp-virtual-mac enabled, both FortiGates would use the same virtual MAC address, ensuring a seamless transition during failover (B). The VRRP domain does not use the physical MAC address (C), and the priority settings indicate that FortiGate-A would be the primary router by default due to its higher priority (D).

For improving reliability over a lossy IPSec tunnel, the fragmentation and fragmentation-mtu parameters should be configured. In scenarios where there might be issues with packet size or an unreliable network, setting the IPsec phase 1 to allow for fragmentation will enable large packets to be broken down, preventing them from being dropped due to size or poor network quality. The fragmentation-mtu specifies the size of the fragments. This is aligned with Fortinet's recommendations for handling IPsec VPN over networks with potential packet loss or size limitations.
