• OSPFv3 VPN extension. (OSPFv3 Type 3, Type 5, and Type 7 LSAs support the DN bit. By default,
OSPFv3 VPN extension uses the DN bit to avoid routing loops.)

• RFC 4659, BGP-MPLS IP Virtual Private Network (VPN) Extension for IPv6 VPN
• RFC 6565, OSPFv3 as a Provider Edge to Customer Edge (PE-CE) Routing Protocol
IPv6 MPLS L3VPN configuration task list
By configuring basic IPv6 MPLS L3VPN, you can construct a simple IPv6 VPN network over an MPLS
backbone.
To deploy special IPv6 MPLS L3VPN networks, such as inter-AS VPN, you must also perform specific
configurations in addition to the basic IPv6 MPLS L3VPN configuration. For more information, see the
related sections.

Configuring basic IPv6 MPLS L3VPN
The key task in IPv6 MPLS L3VPN configuration is to manage the advertisement of IPv6 VPN routes on the
MPLS backbone, including management of PE-CE route exchange and PE-PE route exchange.
To configure basic IPv6 MPLS L3VPN:
Tasks at a glance
Configuring VPN instances :
1. (Required.) Creating a VPN instance
2. (Required.) Associating a VPN instance with an interface
3. (Optional.) Configuring route related attributes for a VPN instance
(Required.) Configuring routing between a PE and a CE
(Required.) Configuring routing between PEs
(Optional.) Configuring BGP VPNv6 route control
Configuration prerequisites
Before configuring basic IPv6 MPLS L3VPN, perform 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.
