ISP_X is IPv4 only in the core with MPLS enabled in the backbone. ISP_X must provide IPv6 services to its customers including IPv6 Internet access.
Which IPv6 transition mechanism allows ISP_X to provide IPv6 connection by levering the existing MPLS core network?
A. Teredo Tunneling
B. NAT64
C. 6PE
D. 6RD
E. ISATAP
in another question, answer was 6to4 tunnels. which one is correct then?
I believe as long as we’re talking MPLS, it’s 6PE. if it was a native IPv4, we’d use 6to4 tunnels
anyone disagree?
