Command
Remarks
6. (Optional.) Configure the
external route tag for
imported VPN routes.
route-tag tag-value
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. HP
recommends that you configure the
same route tag for the same VPN
on the MCEs.
7. Redistribute the VPN routes.
import-route protocol [ process-id
| all-processes | allow-ibgp ] [ cost
cost | route-policy
route-policy-name | tag tag | type
type ] *
By default, OSPF does not
redistribute routes from any other
routing protocol.
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 a
filtering policy to filter
advertised routes.
filter-policy { acl-number |
prefix-list prefix-list-name } export
[ protocol [ process-id ] ]
By default, OSPF does not filter
advertised routes.
10. (Optional.) Configure the
default parameters for
redistributed routes.
default { cost cost | tag tag | type
type } *
The default cost is 1, the default tag
is 1, and the default type 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
Required
By default, an interface does not
run OSPF.

2. Create an IS-IS process
for a VPN instance and
enter IS-IS view.

3. Configure a network
entity title.
network-entity net By default, no NET is configured.
