Designed before the dawn of the commercial Internet, the Border Gateway Protocol (BGP) is a policy-based routing protocol that has long been an established part of the Internet infrastructure. This peering connection is used by border routers in one AS to “advertise” routes to border routers in a different AS (more on this below).

Border Gateway Protocol (more commonly known as BGP ) is the routing protocol that makes the internet work. In this case it was due to more specific prefixes that should not have been advertised. The entire RPKI process stands outside of the BGP routing protocol itself. It’s called RPKI. How Does RPKI Work?

In simple terms, Border Gateway Protocol (BGP) is the protocol that routes traffic on the Internet. During a BGP route hijack, an attacker advertises IP prefixes from an ASN that is not the normal originator. Here we have the DNS clients sending their DNS queries to the hijacked blocks advertised by AS10297.

Unlike dynamic routes, learned through dynamic routing protocols such as OSPF (Open Shortest Path First) or EIGRP (Enhanced Interior Gateway Routing Protocol), static routes require the network administrator to specify the next hop or destination IP address. What is a Static Route? What are the disadvantages of dynamic routing?

BGP The Border Gateway Protocol (BGP) is a protocol for exchanging routing information between different autonomous systems (ASes) on the Internet. Each AS advertises which IP addresses it can route traffic to, helping traffic move from its source AS to the AS closest to its destination.

In particular we’ve learned that speaking or advertising BGP to your service providers and/or peers lets you do two things: Make semi-intelligent routing decisions concerning the best path for a particular route to take outbound from your network (otherwise you would simply set a default route from your border routers into your service providers).
