IPv6 Layer 3 VPNs
The interfaces between the PE and CE routers of a Layer 3 VPN can be configured to carry IP version 6 (IPv6) traffic. IP allows numerous nodes on different networks to interoperate seamlessly. IPv4 is currently used in intranets and private networks, as well as the Internet. IPv6 is the successor to IPv4, and is based for the most part on IPv4.
In the Juniper Networks implementation of IPv6, the service provider implements an MPLS-enabled IPv4 backbone to provide VPN service for IPv6 customers. The PE routers have both IPv4 and IPv6 capabilities. They maintain IPv6 VPN routing and forwarding (VRF) tables for their IPv6 sites and encapsulate IPv6 traffic in MPLS frames that are then sent into the MPLS core network.
IPv6 for Layer 3 VPNs is supported for BGP and for static routes.
IPv6 over Layer 3 VPNs is described in RFC 4659, BGP-MPLS IP Virtual Private Network (VPN) Extension for IPv6 VPN.
For more information about IPv6, see the Junos OS Routing Protocols Configuration Guide.
