Editing Border Gateway Protocol (section)

== Uses ==
BGP4 is standard for Internet routing and required of most [[Internet service provider]]s (ISPs) to establish routing between one another. Very large private [[IP network]]s use BGP internally. An example use case is the joining of a number of large [[Open Shortest Path First]] (OSPF) networks when OSPF by itself does not scale to the size required. Another reason to use BGP is multihoming a network for better redundancy, either to multiple access points to a single ISP or to multiple ISPs.
