In short: BGP (specifically BGP-4) is *the* routing protocol used on the Internet. Think of it as the great-great-great grandnephew of RIP. Network Service Providers and Internet Service Providers use it to advertise IP address reachability to each other. Routers run the protocol between themselves over TCP connections. It's not all that vulnerable to attack - it's biggest problem is that it can be extremely complex to configure properly, which can lead to routing problems across the Internet.
BGP-4 is a standard from the IETF.
