Exam FCSS_EFW_AD-7.6 Topic 3 Question 102 Discussion

Actual exam question for Fortinet's FCSS_EFW_AD-7.6 exam
Question #: 102
Topic #: 3
Refer to the exhibit, which shows an ADVPN network.

An administrator must configure an ADVPN using IBGP and EBGP to connect overlay network 1 with 2.
What two options must the administrator configure in BGP? (Choose two.)

Suggested Answer: A,B Vote an answer

In this ADVPN (Auto-Discovery VPN) network, there are two hubs (Hub A and Hub B) connected via EBGP, while IBGP is used within each overlay. To ensure proper BGP routing between the overlays, the administrator must configure specific BGP options..
set ebgp-enforce-multihop enable
By default, EBGP requires directly connected neighbors. Since Hub A and Hub B are not directly connected but reach each other over an IPsec tunnel, multihop must be enabled for EBGP sessions to work.
set next-hop-self enable
In IBGP, the next-hop attribute does not change by default. When an IBGP route is advertised from a spoke to another hub or spoke, the next-hop needs to be updated to ensure proper reachability. Enabling next-hop-self forces the BGP speaker to advertise itself as the next-hop, ensuring that all spokes properly reach routes across the overlays.
