Internet Engineering Task Force (IETF) X. Vilajosana, Ed. Request for Comments: 8180 Universitat Oberta de Catalunya BCP: 210 K. Pister Category: Best Current Practice University of California Berkeley ISSN: 2070-1721 T. Watteyne Analog Devices May 2017 Minimal IPv6 over the TSCH Mode of IEEE 802.15.4e (6TiSCH) Configuration Abstract This document describes a minimal mode of operation for an IPv6 over the TSCH mode of IEEE 802.15.4e (6TiSCH) network. This minimal mode of operation specifies the baseline set of protocols that need to be supported and the recommended configurations and modes of operation sufficient to enable a 6TiSCH functional network. 6TiSCH provides IPv6 connectivity over a Time-Slotted Channel Hopping (TSCH) mesh composed of IEEE Std 802.15.4 TSCH links. This minimal mode uses a collection of protocols with the respective configurations, including the IPv6 Low-Power Wireless Personal Area Network (6LoWPAN) framework, enabling interoperable IPv6 connectivity over IEEE Std 802.15.4 TSCH. This minimal configuration provides the necessary bandwidth for network and security bootstrapping and defines the proper link between the IETF protocols that interface to IEEE Std 802.15.4 TSCH. This minimal mode of operation should be implemented by all 6TiSCH-compliant devices. Status of This Memo This memo documents an Internet Best Current Practice.
