3.
(Optional.) Specify a default
cost for redistributed routes.

By default, no default route is
redistributed.
This command can only inject
and advertise a default route.
6.
(Optional.) Configure
OSPFv3 to filter redistributed
routes.
filter-policy

By default, OSPFv3 accepts
all redistributed routes.
This command filters only
routes redistributed with the
import-route
command. If the
import-route
command is not
configured, executing this
command does not take
effect.
Tuning and optimizing OSPFv3 networks
This section describes configurations of OSPFv3 timers, interface DR priority, and the logging of
neighbor state changes.
Configuration prerequisites
Before you tune and optimize OSPFv3 networks, complete the following tasks:
•
Configure IPv6 addresses for interfaces to ensure IPv6 connectivity between neighboring nodes.
•
Enable OSPFv3.
