It takes advantage of operational IPv4 MPLSbackbones, eliminating the need for dual-stacking within the MPLScore. Thistranslatesto savings in operational costs and addresses the security limitations of the 6PE approach. 6VPE is more like a regular IPv4 MPLS-VPN provider edge, with an addition of IPv6 support within VRF. It provides logically separate routing table entries for VPN member
