ipv6-address: Specifies an IPv6 network address.

Usage guidelines
Different routing protocols might find different routes to the same destination. However, not all of those
routes are optimal. For route selection, routing protocols, direct routes, and static routes are assigned
different preferences. The route with the highest preference is preferred.
By default, the preference of an EBGP route is lower than a local route. If a device has an EBGP route and
a local route to reach the same destination, the device does not select the EBGP route. You can use the
network shortcut command to configure the EBGP route to have the same preference as the local route
so the EBGP route is more likely to become the optimal route.
You can use the preference command to modify the preferences for external and local BGP routes.
