A fully meshed topology with SD-WAN technology, using dynamic routing and BGP as the routing
protocol, meets the requirements of the company because it provides the following benefits:
It allows direct and secure connectivity between any two branch offices, without the need for a
central hub or intermediary devices12. This reduces the latency and improves the performance of
the critical business applications.
It leverages SD-WAN technology to optimize the traffic flow and application quality of service (QoS)
across the WAN13. SD-WAN can dynamically select the best path for each application based on the
network conditions and policies13. SD-WAN can also provide redundancy, security, and visibility for
the WAN13.
It uses dynamic routing and BGP as the routing protocol to exchange routing information and
establish connectivity between the branch offices14. BGP is a scalable and flexible protocol that can
support multiple address families, such as IPv4 and IPv6, and multiple routing policies, such as local
preference and route filtering14. BGP can also enable seamless integration with the cloud service
providers (CSPs) and internet service providers (ISPs)14.
