🌐 Phase 9 · IPv6 Transition & Dual-Stack Infrastructure¶
🚀 100% Local Enterprise & SP IPv6 Masterclass: From IPv6 Neighbor Discovery (ND) and SLAAC to BGP Unnumbered over IPv6 Link-Local (RFC 5549 / RFC 8950), 6PE/6VPE over MPLS, and Stateful NAT64/DNS64 translation.
🏛️ Course Architecture & IPv6 Roadmap¶
Transitioning to IPv6-only data center underlays and dual-stack enterprise edges eliminates IPv4 address exhaustion, NAT friction, and operational overhead. Phase 9 teaches you how to build 100% local, self-contained IPv6 network architectures:
