What is BGP?What is BGP?Posted Apr 22, 2004 18:09 UTC (Thu) by pflugstad (subscriber, #224)In reply to: Thanks by vondo Parent article: TCP vulnerability: cancel red alert 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.
