Routing protocols such as RIP (Routing Information Protocol) or OSPF (Open Shortest Path First) serve to pass on changes to routes between two networked systems to the systems concerned, thereby making s a dynamic change of the routing tables possible. It is easily possible to generate incorrect RIP packets and thus to configure undesirable routes.
The use of dynamic routing makes it possible to send routing information to a computer which usually uses this information unchecked to build up its routing tables. The invader can exploit this to change the transmission route in a particular way.
