BGP (Border Gateway Protocol)
The routing protocol that connects networks to each other and to the internet and cloud providers, exchanging reachable prefixes between autonomous systems.
In REAP
BGP sessions, received and advertised prefixes and route changes are evidence for WAN, cloud-interconnect and data-center investigations.
