Explanation
When configuring a loopback interface as the BGP source for connecting to an ISP, two important settings must be applied: 1. Enable EBGP Multihop (ebgp-enforce-multihop) BGP normally expects directly connected neighbors, but since the ISP and FortiGate A are using loopback interfaces, packets will not be sent directly between their physical interfaces. The ebgp- enforce-multihop command allows BGP to form an eBGP peering over multiple hops. 2. Set the Update Source (update-source) Since FortiGate is using a loopback interface as the source, the update-source command ensures that BGP updates originate from the loopback interface rather than a physical interface. This is essential because BGP peers must match the source IP with the configured neighbor
