1068 Configuring IPv6 Routing
Figure 37-8. IPv6 Route Table
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.
To display the page, click Routing → IPv6 → IPv6 Routes → IPv6 Route
Preferences in the navigation panel.
