Step Command

Remarks

8.

(Optional.) Configure OSPF
to redistribute the default

route.

default-route-advertise summary
cost cost

By default, OSPF does not
redistribute the default route.
This command redistributes the
default route in a Type-3 LSA. The

MCE advertises the default route to

the PE.

9.

(Optional.) Configure filtering

of advertised routes.

filter-policy { acl-number |
prefix-list prefix-list-name } export
[ protocol [ process-id ] ]

By default, redistributed routes are
not filtered.

10.

(Optional.) Configure the
default parameters for

redistributed routes (cost,
route number, tag, and type).

default { cost cost | tag tag | type
type } *

The default cost is 1, the default tag
is 1, and default type of
redistributed routes is Type-2.

11.

Create an OSPF area and
enter OSPF area view.

area area-id

By default, no OSPF area is
created.

12.

Enable OSPF on the interface
attached to the specified

network in the area.

network ip-address wildcard-mask

By default, an interface neither
belongs to any area nor runs

OSPF.

If you do not specify the route level

in the command, the command
redistributes routes to the level-2

routing table by default.
