Several dynamic routing protocols could run simultaneously on a router. In this case,
there is an issue of sharing and selecting the routing information among all the routing
protocols. The system sets a preference for each routing protocol. When various
routing protocols find the route to the same destination, the protocol with the higher
preference will take effect.
