I think this (LPD over ipv6) is not a customer (isp/carrier) demand but a real problem when RIRs stop to allocate ipv4 addresses. How ISP/Carriers can build a new mpls backbone If big vendor not support the IPv6 over LDP and isp can't make request for new ipv4 blocks ?

Our idea is to use ipv6 for backbone mpls and mpls vpn to holding old ipv4 customers and all ipv4 networks inside vpn BUT today LDP work only with IPv4. So now we can't use ipv6 for mpls and we have still use ipv4 addresses to run ldp on backbone and 6vpe for vpn.
