Step
4. (Optional.) Configure the
OSPF domain ID.
5. (Optional.) Configure the type
codes of OSPF extended
community attributes.
6. (Optional.) Configure the
external route tag for
imported VPN routes.
7. Redistribute the VPN routes.
8. (Optional.) Configure OSPF
to redistribute the default
route.
9. (Optional.) Configure a
filtering policy to filter the
redistributed routes.
10. (Optional.) Configure the
default parameters for
redistributed routes.
11. Create an OSPF area and
enter OSPF area view.
12. Enable OSPF on the interface
attached to the specified
network in the area.
For more information about OSPF, see Layer 3—IP Routing Configuration Guide.

Remarks
By default, the domain ID is 0.
The defaults are as follows:
•
0x0005 for Domain ID.
•
0x0107 for Router ID.
•
0x0306 for Route Type.
By default, no route tag is
configured.
In some networks, a VPN might be
connected to multiple MCEs.
When one MCE advertise the
routes learned from BGP to the
VPN, the other MCEs might learn
the routes, resulting in routing
loops. To avoid such routing loops,
you can configure route tags for
VPN instances on an MCE. H3C
recommends configuring the same
route tag for the same VPN on the
MCEs.
By default, no route of any other
routing protocol is redistributed
into OSPF.
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.
By default, redistributed routes are
not filtered.
The default cost is 1, the default tag
is 1, and the default type is Type-2.
By default, no OSPF area is
created.
Required
By default, an interface does not
run OSPF.
