Configuring VPN instances

By configuring VPN instances on a PE, you isolate not only VPN routes from public network routes, but
also routes of a VPN from those of another VPN. 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.
To create and configure a VPN instance:
Step
1. Enter system view.
2. Create a VPN instance and
enter VPN instance view.
3. Configure an RD for the VPN
instance.
4. Configure a description for
the VPN instance.
Associating a VPN instance with an interface
After creating and configuring a VPN instance, you must associate the VPN instance with the interface
for connecting the CE. Any LDP-capable interface can be associated with a VPN instance. For
information about LDP-capable interfaces, see
To associate a VPN instance with an interface:
Step
1. Enter system view.
2. Enter interface view.
3. Associate a VPN instance
with the interface.
NOTE:
The ip binding vpn-instance command clears the IP address of the interface on which it is configured. Be
sure to re-configure an IP address for the interface after configuring the command.
