Abstract Abstract
In order to transmit IPv6 packets on IEEE 802.11 networks running In order to transmit IPv6 packets on IEEE 802.11 networks running
outside the context of a basic service set (OCB, earlier "802.11p") outside the context of a basic service set (OCB, earlier "802.11p")
there is a need to define a few parameters such as the supported there is a need to define a few parameters such as the supported
Maximum Transmission Unit size on the 802.11-OCB link, the header Maximum Transmission Unit size on the 802.11-OCB link, the header
format preceding the IPv6 header, the Type value within it, and format preceding the IPv6 header, the Type value within it, and
