HP 10500 Series Configuration Manual page 114

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.) Configure 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.
Configuring IS-IS between a PE and a CE
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

Remarks
N/A
Perform this configuration on the
PE. On the CE, create a common
OSPF process.
The default domain ID is 0.
Perform this configuration on the
PE. On the CE, configure common
OSPF.
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 VPN routes.
An OSPF process can be
configured with only one domain
ID. Domain IDs of different OSPF
processes are independent of each
other.
All OSPF processes of a VPN must
be configured with the same
domain ID, while OSPF processes
on PEs in different VPNs can be
configured with domain IDs as
desired.
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 area is
created.
By default, an interface neither
belongs to any area nor runs
OSPF.
