Configuring a priority for OSPFv3
A router may 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.

By default, the priority of OSPFv3 internal

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 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 be advertised in LSAs into the
routing domain.
•
Using 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.
