1.  Introduction

   Vehicular networking has become popular by the enhancement of
   Intelligent Transportation Systems (ITS) [ISO-ITS-IPv6].  The
   vehicular networking can work based on Dedicated Short-Range
   Communications (DSRC) [DSRC].  This DSRC is realized by the IEEE
   Wireless Access in Vehicular Environments (WAVE) [WAVE-1609.0].
   Especially, IEEE 802.11-OCB (Outside the Context of Basic Support
   Set) [IEEE-802.11-OCB] provides the Media Access Control (MAC) for
   vehicles in vehicular networks.  IP-based vehicular networking can be
   supported with IPv6 over IEEE 802.11-OCB [RFC8691], which defines the
   IPv6 Neighbor Discovery (ND), Maximum Transmission Unit (MTU), and
   MAC layer adaptation.

   Vehicles can construct Vehicular Ad Hoc Networks (VANET) by
   themselves without any infrastructure node such as a Road-Side Unit
   (RSU).  Cooperative Adaptive Cruise Control and Autonomous Driving
   (i.e., Self-Driving) services can take advantage of this vehicular
   networking for safe driving through the wireless communications among
