Configuring Multi-Vpn-Instance; Configuring Vpn Instances - H3C S5800 Series Configuration Manual

Route Exchange between MCE and PE
Routing information entries are bound to specific VPN instances on an MCE device, and packets of
each VPN instance are forwarded between MCE and PE according to interface. As a result, VPN
routing information can be transmitted by performing relatively simple configurations between MCE
and PE, such as importing the VPN routing entries on MCE devices to the routing table of the routing
protocol running between MCE and PEs.
The following routing protocols can be used between MCE and PE for routing formation exchange:
Static route
RIP
OSPF
IS-IS
EBGP
For information on how to configure the routing protocols and how to import routes, see relevant
chapters in the Layer 3 - IP Routing Configuration Guide.
Configuring Multi-VPN-Instance CE

Configuring VPN Instances

VPN instances are used to isolate VPN routes from public network routes. Configuring VPN instances
is required in all MCE networking schemes.
In addition, routes of a VPN instance are isolated from those of another. This feature allows VPN
instances to be used in networking schemes other than MCE.
This section includes the following configurations:
Creating a VPN Instance
Associating a VPN Instance with an Interface
Configuring Route Related Attributes of a VPN Instance
Creating a VPN Instance
A VPN instance is associated with a site, rather than a VPN. It is a collection of the VPN membership
and routing rules of its associated site.
A VPN instance takes effect only after you configure an RD for it. Before configuring an RD for a VPN
instance, you can configure no parameters for the instance other than a description.
A VPN instance description is a piece of descriptive information about the VPN instance. You can use it
to keep information such as the relationship of the VPN instance with a VPN.
Follow these steps to create and configure a VPN instance:
To do...
Enter system view
Create a VPN instance and enter
VPN instance view
Configure an RD for the VPN
instance
Use the command...
system-view
ip vpn-instance
vpn-instance-name
