Parameters
ase: Sets a preference for OSPF external routes. Without this keyword, the command sets a preference
for OSPF internal routes.
route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63
characters, to set a preference for the specified routes.
value: Specifies the preference value in the range of 1 to 255. The smaller the value, the higher the
preference.
Usage guidelines
If multiple routing protocols find routes to the same destination, the router uses the route found by the
protocol with the highest preference.
