3. Configure OSPF to
redistribute routes from
another routing protocol.
import-route
protocol [ as-number ]
[ process-id |
all-processes

allow-ibgp
] [
allow-direct
|
cost
cost-value |
nssa-only
|
route-policy
route-policy-name |
tag

type
type ]
*
By default, no route
redistribution is configured.
This command redistributes only
active routes. To view
information about active routes,
use the
display ip routing-table
command.
4. (Optional.) Configure
OSPF to filter
redistributed routes.
filter-policy
{ ipv4-acl-number |
prefix-list
prefix-list-name }
export
[ protocol [ process-id ] ]
By default, OSPF accepts all
redistributed routes.
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:
1. Enter system view.
N/A
2. Enter OSPF view.
ospf
[
process-id |
router-id
router-id |
vpn-instance
vpn-instance-name ] *
N/A
3. Redistribute a default
route.
default-route-advertise

permit-calculate-other
] |
cost
cost-value |
route-policy
route-policy-name
|
type
type
] *
default-route-advertise
[
summary
cost-value ]
By default, no default route is
redistributed.
This command is applicable
only to VPNs. The PE router
advertises a default route in a
Type-3 LSA to a CE router.
Configuring default parameters for redistributed routes
Perform this task to configure default parameters for redistributed routes, including cost, tag, and
type. Tags identify information about protocols. For example, when redistributing BGP routes, OSPF
uses tags to identify AS IDs.
To configure the default parameters for redistributed routes:
1. Enter system view.
system-view
N/A
2. Enter OSPF view.
ospf
[
process-id |
router-id
router-id |
vpn-instance
vpn-instance-name ] *
N/A
3. Configure the default
parameters for
redistributed routes
(cost, upper limit, tag,
and type).
default
{
cost
cost-value |
tag
tag |
type
type } *
By default, the cost is 1, the tag
is 1, and the type is Type-2.
