In MikroTik, which protocol is used for dynamic routing?

Dynamic routing protocols are designed to automatically update and maintain routing tables in greater network configurations. Among the choices provided, BGP, or Border Gateway Protocol, is specifically tailored for inter-domain routing across the internet and among various autonomous systems. It allows routers to communicate with each other to exchange routing information dynamically, adapting to changes in the network, such as link failures or changes in network topology.

BGP employs path vector mechanisms, making it suitable for large and complex network environments where maintaining routes manually would be labor-intensive and prone to errors. Other protocols like SMTP (Simple Mail Transfer Protocol), IMAP (Internet Message Access Protocol), and HTTP (Hypertext Transfer Protocol) are designed for specific application layer tasks related to email and web traffic, respectively, rather than for the purpose of routing data packets dynamically across a network. Thus, BGP is the clear choice for dynamic routing in the context of MikroTik and networking standards.
