This post transitions to native IPv6 routing using <strong>OSPFv3 (RFC 5340)</strong> on Nokia SR OS.</p> <p>OSPFv3 decouples protocol operations from IPv4 addressing semantics. It runs on a per-link basis rather than a per-subnet basis, negotiates adjacencies over IPv6 Link-Local addresses, and introduces separate Link-State Advertisement (LSA) types to decouple topological structure from IP prefix reachability.</p>
