Description: A boundary router is a network device that serves as a connection point between different autonomous systems (AS) in the context of the Internet. Its primary function is to manage the flow of data traffic entering and leaving an autonomous system, ensuring that information is directed correctly to its destination. These routers are essential for communication between networks, as they enable interoperability between different protocols and network architectures. Boundary routers use routing protocols such as BGP (Border Gateway Protocol) to exchange routing information and optimize data paths. Additionally, they are responsible for implementing routing policies, controlling how data is distributed, and ensuring compliance with security and quality of service rules. In summary, a boundary router is a critical component in network infrastructure, facilitating connectivity and efficiency in data transmission between different networks and autonomous systems.
