Configuring a priority for OSPFv3
A router can run multiple routing protocols. The system assigns a priority to each protocol. When these
routing protocols find the same route, the route found by the protocol with the highest priority is selected.

3.
Configure a priority for
OSPFv3.
preference [ ase ] [ route-policy
route-policy-name ] preference
Optional.
By default, the priority of OSPFv3 internal
routes is 10, and the priority of OSPFv3
external routes is 150.
Configuring OSPFv3 route redistribution
Follow these guidelines when you configure OSPFv3 route redistribution:
•
Executing the import-route or default-route-advertise command on a router makes it become an
ASBR.
•
You can only inject and advertise a default route by using the default-route-advertise command.
•
Because OSPFv3 is a link state routing protocol, it cannot directly filter LSAs to be advertised; you
must filter redistributed routes first. Routes that are not filtered out can then be advertised in LSAs.
•
The filter-policy export command filters routes redistributed with the import-route command. If the
import-route command is not configured, executing the filter-policy export command does not take
effect.
