IPv6 Route Preferences
Use this page to configure the default preference for each protocol. These values are
arbitrary values in the range of 1 to 255 and are independent of route metrics. Most routing
protocols use a route metric to determine the shortest path known to the protocol,
independent of any other protocol. The best route to a destination is chosen by selecting the
route with the lowest preference value. When there are multiple routes to a destination, the
preference values are used to determine the preferred route. If there is still a tie, the route
with the best route metric is chosen. To avoid problems with mismatched metrics you must
configure different preference values for each of the protocols.
