3. Configure a preference
for OSPFv3.

By default, the preference of OSPFv3
internal routes is 10, and the priority of
OSPFv3 external routes is 150.
Configuring OSPFv3 route redistribution
Because OSPFv3 is a link state routing protocol, it cannot directly filter LSAs to be advertised.
OSPFv3 filters only redistributed routes. Only routes that are not filtered out can be advertised in
LSAs.
Redistributing routes from another routing protocol
IMPORTANT:
The import-route bgp4+ command redistributes only EBGP routes. Because the import-route
bgp4+ allow-ibgp command redistributes both EBGP and IBGP routes, and might cause routing
loops, use it with caution.
To configure OSPFv3 route redistribution:

2. Enter OSPFv3 view.

3. Configure OSPFv3 to
redistribute routes from other
routing protocols.
import-route

By default, route
redistribution is disabled.
4. (Optional.) Configure
OSPFv3 to filter redistributed
routes.
filter-policy
{ acl6-number |
prefix-list
prefix-list-name }
export
[ protocol
[ process-id ] ]
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.
Redistributing a default route
The import-route command cannot redistribute a default external route. Perform this task to
redistribute a default route.
To redistribute a default route:
