Step
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, while 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 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 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.
5. Enter interface view.
6. Enable the IS-IS process on
the interface.
For more information about IS-IS, see Layer 3—IP Routing Configuration Guide.
