To do...
Create an OSPF area and enter
area view
Enable OSPF on the interface
attached to the specified network
in the area
NOTE:
Deleting a VPN instance also deletes all the related 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.
NOTE:
For more information about OSPF, see
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.
To configure IS-IS between PE and CE:
To do...
Enter system view
Create an IS-IS process for a VPN
instance and enter IS-IS view
Configure a network entity title for
the IS-IS process
Return to system view
Enter interface view
Enable the IS-IS process on the
interface
NOTE:
