    abstract =  {This document defines a mechanism to use IPv4 to transport OSPFv3 packets, in order to facilitate transition from IPv4-only to IPv6 and dual-stack within a routing domain. Using OSPFv3 over IPv4 with the existing OSPFv3 Address Family extension can simplify transition from an OSFPv2 IPv4-only routing domain to an OSPFv3 dual-stack routing domain.},
