A housing authority must extend IPv6 civic services across an MPLS core. Which approaches are conceptually appropriate at the PE layer?
Select an answer to reveal the explanation.
Short Explanation
IPv6 can ride the same MPLS rails—either as VPNv6 inside VRFs or via 6PE-style labeled IPv6. You don’t have to melt the MPLS core or NAT everything to IPv4 at the CE first. Pick the PE address-family approach that matches the design.
Full Explanation
Extending IPv6 across an MPLS core commonly uses MP-BGP VPNv6 for VRF-aware L3VPN or 6PE-style labeled IPv6 unicast over the existing MPLS underlay. Those approaches preserve MPLS transport while signaling IPv6 reachability at the PE layer. Disabling MPLS for multicast-only transport, mandatory CE NAT64/NAT44 translation, or RIPng-only P-core designs are not the standard PE solutions for this requirement.
