Displaying the IPv6 Route Table Using CLI Commands
For information about the CLI commands that perform this function, see the following chapter in the

:
• IPv6 Routing Commands
The following table summarizes the equivalent CLI commands for this feature.
IPv6 Route Preferences
Use the IPv6 Route Preferences
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.
