Technology explained

What is BGP?

Border Gateway Protocol is the routing protocol used to exchange reachability information between autonomous systems and large routed networks. This profile connects the concept to KBY's practical engineering guidance.

BGP selects paths using policy and attributes rather than simple shortest-path calculation. Its sessions advertise prefixes incrementally, making filtering, convergence, route validation and policy design central to Internet and multi-homed network stability.

Primary purpose

Exchange policy-controlled network routes between independently managed routing domains.
