You collected the output displayed in the exhibits and need to determine which interface HTTP traffic from user device 10.0.1.101 to corporate web server 10.0.0.126 will traverse.

All SD-WAN links are stable.

Which interface will FortiGate use to steer the traffic?

Explanation

Traffic to 10.0.0.126 from 10.0.1.101 matches the Corp SD-WAN service. That service enables load balancing and includes member sequence numbers 3, 4, and 5. The policy-route entry maps those eligible members to HUB1-VPN1, HUB1-VPN2, and HUB1-VPN3 and specifies the round-robin hash mode. With every link stable, FortiGate can distribute matching HTTP sessions across any of those three VPN interfaces; one observed ICMP flow on HUB1-VPN3 does not constrain the HTTP traffic to that interface.
