Configuring VPN instances
VPN instances isolate not only VPN routes from public network routes, but also routes among VPNs. This
feature allows VPN instances to be used in network scenarios besides MPLS L3VPNs.
All VPN instance configurations are performed on PEs or MCEs.
Creating a VPN instance
A VPN instance is associated with a site. It is a collection of the VPN membership and routing rules of its
associated site. A VPN instance does not necessarily correspond to one VPN.

Command Remarks
1. Enter system view.
system-view N/A
2. Create a VPN instance and
enter VPN instance view.

3. Configure an RD for the VPN
instance.

A VPN instance takes effect only
after you configure an RD for it.
4. Configure a description for
the VPN instance.
description text
Optional.
The description should contain the
VPN instance's related
information, such as its relationship
with a certain VPN.
Associating a VPN instance with an interface
After creating and configuring a VPN instance, associate the VPN instance with the interface connected
to the CE. Any LDP-capable interface can be associated with a VPN instance. For information about
LDP-capable interfaces, see "Configuring basic MPLS."
