• Configure MPLS LDP on PEs and Ps to establish LDP LSPs.

Configuring VPN instances

By configuring VPN instances on a PE, you isolate not only VPN routes from public network routes, but
also routes between VPNs. This feature allows VPN instances to be used in network scenarios besides
MPLS L3VPNs.
All VPN instance configurations are performed on PEs.
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 might correspond to more than 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. (Optional.) Configure a
description for the VPN
instance.
5. (Optional.) Configure an ID
for the VPN instance.
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.
To associate a VPN instance with an interface:
Step
1. Enter system view.
2. Enter interface view.
