Border Gateway Protocol or BGP is a steering protocol, which is used for the transmission of data and information between various host gateways, the Internet or autonomous systems. BGP is defined as a Path Vector Protocol (PVP), which helps in maintaining paths to different hosts, networks and gateway routersSometimes, BGP is described as a reachability protocol rather than a routing protocol. BGP roles include:

- Being a PVP, BGP communicates the entire autonomous system or network path topology to other networks

- Maintains its routing table with topologies of all externally connected networks

- Supports classless inter-domain routing (CIDR), which allocates Internet Protocol (IP) addresses to connected Internet devices
