Task Remarks
Configuring VPN instances
Creating a VPN instance Required.
Associating a VPN instance with an interface Required.
Configuring route related attributes for a VPN
instance
Optional.
Configuring a tunneling policy for a VPN instance Optional.
Configuring an LDP instance Optional.
Configuring routing between a PE and a CE Required.
Configuring routing between PEs Required.
Configuring routing features for the BGP-VPNv6 subaddress family Optional.
Before configuring basic IPv6 MPLS L3VPN, complete the following tasks:
• Configure an IGP on the PEs and Ps to ensure IP connectivity within the MPLS backbone.
• Configure basic MPLS for the MPLS backbone
• 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 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:

Associating a VPN instance with an interface
After creating and configuring a VPN instance, associate the VPN instance with the interface for
connecting the CE. Any LDP-capable interface can be associated with a VPN instance. For more
information about LDP-capable interfaces, see "Configuring basic MPLS."
