+ | ===== What is BGP ===== | ||
+ | |||
+ | The Border Gateway Protocol (BGP) is the routing protocol of the Internet. For any operator wishing to enter into a peering relationship with another operator, BGP will almost always be required. | ||

+ | As soon as the local network obtains a connection to another network they become what is know as **multihomed**, | ||
