    abstract =  {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.},
