NOTE:
• The maximum number of OSPF processes that a router supports is 10. The maximum number of OSPF
processes for a VPN instance is 10.
• 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.
For more information about IS-IS, see Layer 3—IP Routing Configuration Guide.
To configure PE-CE route exchange through IS-IS:

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.

5. Enter interface view.

6. Enable the IS-IS process on
the interface.

Configuring EBGP between a PE and a CE
1. Configure the PE:

4. Configure the CE as the VPN
EBGP peer.
