What does BGP enable between FortiSASE and the FortiGate SD-WAN hub?

BGP, or Border Gateway Protocol, is instrumental in facilitating the exchange of routing information between networks. In the context of FortiSASE and the FortiGate SD-WAN hub, BGP plays a crucial role in ensuring that routing paths remain optimal and traffic is managed efficiently across the network. By leveraging BGP, these systems can dynamically communicate about network changes and the availability of different paths, allowing for adaptive routing that can respond to network fluctuations. This capability supports load balancing, failover solutions, and overall enhanced performance for the SD-WAN infrastructure.

The primary purpose of BGP in this scenario is not focused on encrypting data packets, monitoring network performance, or establishing VPN connections—areas that are covered by other protocols and technologies. While encryption is vital for data security, it is not a function of BGP itself; instead, this is typically managed by protocols designed specifically for secure communication. Similarly, monitoring tools or solutions separately manage performance analytics, and VPNs use other tunneling protocols to establish secure connections. Thus, the focus of BGP's functionality is very much aligned with routing and traffic management, making it the best answer in this context.
