I. Chen: AUTHOR [+3]
Using OSPFv3 [RFC5340] over IPv4 [RFC791] with the existing OSPFv3 address family extension can simplify transition from an IPv4-only routing domain to an IPv6 [RFC2460] or dual-stack routing domain. Dual-stack routing protocols, such as the Border Gateway Protocol [RFC4271], have an advantage during the transition, because both IPv4 and IPv6 address families can be advertised using either IPv4 or IPv6 transport. Some IPv4-specific and IPv6-specific routing protocols share enough similarities in their protocol packet formats and protocol signaling that it is trivial to deploy an initial IPv6 routing domain by transporting the routing protocol over IPv4, thereby allowing IPv6 routing domains to be deployed and tested before decommissioning IPv4 and moving to an IPv6-only network.

OSPFv3 over IPv4 for IPv6 Transition
This document defines a mechanism to use IPv4 to transport OSPFv3 packets. Using OSPFv3 over IPv4 with the existing OSPFv3 Address Family extension can simplify transition from an OSPFv2 IPv4-only routing domain to an OSPFv3 dual-stack routing domain. This document updates RFC 5838 to support virtual links in the IPv4 unicast address family when using OSPFv3 over IPv4.
