Introduction This document describes the transmission of IPv6 packets on IEEE Std 802.11-OCB networks [IEEE-802.11-2016] (a.k.a "802.11p" see Appendix B). This involves the layering of IPv6 networking on top of the IEEE 802.11 MAC layer, with an LLC layer. Compared to running IPv6 over the Ethernet MAC layer, there is no modification expected to IEEE Std 802.11 MAC and Logical Link sublayers: IPv6 works fine directly over 802.11-OCB too, with an LLC layer. @@ -198,24 +198,23 @@ [I-D.ietf-ipwave-vehicular-networking-survey], that lists some scenarios and requirements for IP in Intelligent Transportation Systems. The link model is the following: STA --- 802.11-OCB --- STA. In vehicular networks, STAs can be RSRUs and/or OBRUs. While 802.11-OCB is clearly specified, and the use of IPv6 over such link is not radically new, the operating environment (vehicular networks) brings in new perspectives. - The 802.11-OCB links form and terminate; nodes connected to these - links peer, and discover each other; the nodes are mobile.

IPv6 over 802.11-OCB 4.1. Maximum Transmission Unit (MTU) The default MTU for IP packets on 802.11-OCB is 1500 octets. It is the same value as IPv6 packets on Ethernet links, as specified in [RFC2464]. This value of the MTU respects the recommendation that every link on the Internet must have a minimum MTU of 1280 octets (stated in [RFC8200], and the recommendations therein, especially @@ -521,25 +520,20 @@ participants to discussions in network working groups.
