C onfiguring OSPF between a PE and a CE
4 6 8 B
An OSPF process that is bound to a VPN instance does not use the public network router ID
configured in system view. Therefore, you must specify a router ID when creating a process or
configure an IP address for a minimum of one interface in the VPN instance.
An OSPF process belongs to the public network or a single VPN instance. If you create an OSPF
process without binding it to a VPN instance, the process belongs to the public network.
To configure OSPF between a PE and a CE:
Step
1. Enter system view.
2. Create an OSPF process for
a VPN instance and enter the
OSPF view.
3. (Optional.) Set an OSPF
domain ID.
4. Configure the type codes of
OSPF extended community
attributes.
5. Create an OSPF area and
enter area view.
6. Enable OSPF on the
interface attached to the
specified network in the area.
C onfiguring IS-IS between a PE and a CE
4 6 9 B
An IS-IS process belongs to the public network or a single VPN instance. If you create an IS-IS
process without binding it to a VPN instance, the process belongs to the public network.
To configure IS-IS between a PE and a CE:
Command
system-view
ospf [ process-id | router-id
router-id | vpn-instance
vpn-instance-name ] *
domain-id domain-id
[ secondary ]
ext-community-type
{ domain-id type-code1 |
router-id type-code2 | route-type
type-code3 }
area area-id
network ip-address

Remarks
N/A
Perform this configuration on the
PE. On the CE, create a common
OSPF process.
Deleting a VPN instance also
deletes all related OSPF
processes.
The default domain ID is 0.
Perform this configuration on the
PE.
The domain ID is carried in the
routes of the OSPF process.
When redistributing routes from
the OSPF process, BGP adds the
domain ID as an extended
community attribute into BGP
routes.
An OSPF process can be
configured with only one primary
domain ID. Domain IDs of
different OSPF processes can be
the same.
All OSPF processes of a VPN
must be configured with the same
domain ID.
The defaults are as follows:
•
0x0005 for Domain ID.
•
0x0107 for Router ID.
•
0x0306 for Route Type.
Perform this configuration on the
PE.
By default, no OSPF areas exist.
By default, an interface neither
belongs to any area nor runs
OSPF.
