VPN instances are used to isolate VPN routes from public network routes.
Configuring VPN instances is required in all MPLS L3VPN 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 MPLS
L3VPNs.
All VPN instance configurations are on PEs.
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
Configure a description for the VPN
instance
After creating and configuring a VPN instance, you associate the VPN instance
with the interface for connecting CEs. Any interface supporting MPLS LDP
capability can be associated with a VPN instance. For interfaces supporting MPLS
LDP capability, refer to
