Step
2. Create an OSPF process for a
VPN instance and enter the
OSPF view.
3. Configure the 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.
NOTE:
Deleting a VPN instance also deletes all the associated OSPF processes.
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 for routes to be correctly
advertised, but OSPF processes on PEs in different VPNs can be configured with domain IDs as desired.
The domain ID of an OSPF process is included in the routes generated by the process. When an OSPF
route is redistributed into BGP, the OSPF domain ID is included in the BGP VPN route and delivered as
a BGP extended community attribute.
For more information about OSPF, see Layer 3—IP Routing Configuration Guide.
Configuring IS-IS between PE and 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.
For more information about IS-IS, see Layer 3—IP Routing Configuration Guide.
To configure PE-CE route exchange through IS-IS:
Step
1. Enter system view.
2. Create an IS-IS process for a
VPN instance and enter IS-IS
view.
3. Configure a network entity
title for the IS-IS process.
4. Return to system view.

Remarks
Perform the configurations on PEs.
On CEs, create a normal OSPF
process.
Optional.
0 by default.
Optional.
The defaults are as follows:
•
0x0005 for Domain ID.
•
0x0107 for Router ID.
•

Perform this configuration on PEs.
By default, no OSPF area is
created.
By default, an interface neither
belongs to any area nor runs
OSPF.
