Assignment of an Ethertype for IPv6 with LoWPAN Encapsulation Assignment of an Ethertype for IPv6 with
draft-ietf-6lo-ethertype-request-01 Low-Power Wireless Personal Area Network (LoWPAN) Encapsulation
Abstract Abstract
When carried over layer 2 technologies such as Ethernet, IPv6 When carried over Layer 2 technologies such as Ethernet, IPv6
datagrams using LoWPAN encapsulation as defined in RFC 4944 must be datagrams using Low-Power Wireless Personal Area Network (LoWPAN)
identified so the receiver can correctly interpret the encoded IPv6 encapsulation as defined in RFC 4944 must be identified so the
datagram. This document requests the assignment of an Ethertype for receiver can correctly interpret the encoded IPv6 datagram. The IETF
that purpose. officially requested the assignment of an Ethertype for that purpose
and this document reports that assignment.

2. Request to IEEE for assignment of an Ethertype 2. Assignment of an Ethertype by IEEE
When this document is published, the IETF will formally submit a The IETF formally submitted a request to IEEE for assignment of an
request to IEEE for assignment of an Ethertype for IPv6 datagrams Ethertype for IPv6 datagrams using LoWPAN encapsulation. IEEE has

The assignment has been recorded by IEEE [IEEE-ETHERTYPES].
