Question
An engineer is asked to propose a solution that can offer VPN IPv6 services over the IPv4 MPLS network of a Service Provider. The design must require the minimum configuration changes and eliminate the need for dual-stacking within the IPv4/MPLS core. Which IPv6 transition strategy does the engineer recommend?
Options
- A6PE
- Bstateless NAT54

Explanation
01s_chapter_0100001.pdf 6VPE is a mechanism to use the IPv4 backbone to provide VPN IPv6 services. 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
