12. Quality of Service

Since all the QoS mechanisms discussed for IPv4 VPNs in Section 14 of [BGP/MPLS-VPN] operate in the same way for IPv4 and IPv6 (Diffserv, Intserv, MPLS Traffic Engineering), the QoS considerations discussed in [BGP/MPLS-VPN] are equally applicable to IPv6 VPNs (and this holds whether IPv4 tunneling or IPv6 tunneling is used in the backbone.)
