When routes to the same destination are found by multiplerouting protocols, the route learned by the protocol with the highest priority wins. You can reference arouting policy to specify a priority for specific routes. For information about routing policy, refer toRouting Policy Configuration in the IP Routing Volume.Follow these steps to configure the priority of IS-IS.
