Which two routing protocols can be used by the vEdge router to learn reachability information from service-side interfaces?

The vEdge router can utilize BGP (Border Gateway Protocol) and OSPF (Open Shortest Path First) to learn reachability information from service-side interfaces due to their characteristics as exterior and interior routing protocols, respectively.

BGP is widely used for inter-domain routing, allowing the vEdge router to exchange routing information with other BGP-enabled routers across different autonomous systems. This protocol is particularly useful in large-scale environments and on the internet, enabling efficient route management and path selection based on various attributes and policies.

Meanwhile, OSPF is an interior gateway protocol (IGP) designed for use within a single administrative domain. It uses a link-state routing algorithm, allowing routers to maintain a complete and accurate view of the network topology. When deployed, OSPF enables the vEdge router to quickly learn and propagate reachability information among routers in the same area or multiple areas, ensuring effective routing decisions based on the shortest path.

Together, BGP and OSPF facilitate comprehensive routing reachability for service-side interfaces, making them suitable for the requirements posed by applications using the vEdge router in a versatile network architecture, which may span multiple routing domains or require efficient traffic management within an organization’s local network.
