OSPFv3
OSPFv3 is required for IPv6 network deployments. If you're dual-stacking or going IPv6-only, you'll need OSPFv3 alongside or replacing OSPFv2.
What It Defines
OSPFv3 adapts OSPF for IPv6 with architectural changes: link-local addressing for neighbor discovery, removal of IPv4-specific fields, Address Family (AF) support for both IPv4 and IPv6 via RFC 5838, and IPsec-based authentication per-interface. Operationally similar to OSPFv2 but with IPv6 semantics throughout.
Canonical (Normative)
The canonical publication point for finalized RFCs. If a protocol is standardized as an RFC, the RFC Editor text is the normative final reference. Published by the IETF, IRTF, IAB, and independent stream.
