Since a router may run multiple dynamic routing protocols, it has to decide on routes
found by these protocols. Every protocol has a priority to help the router determine
which route to use especially when multiple routes to the same destination are found by
several routing protocols. The route found by the protocol with the highest priority will
be used.
