Abstract Abstract
This specification updates RFC 6775 - 6LoWPAN Neighbor Discovery, to This specification updates RFC 6775 - 6LoWPAN Neighbor Discovery, to
clarify the role of the protocol as a registration technique, clarify the role of the protocol as a registration technique,
simplify the registration operation in 6LoWPAN routers, as well as to simplify the registration operation in 6LoWPAN routers, as well as to
provide enhancements to the registration capabilities and mobility provide enhancements to the registration capabilities and mobility

extends the format defined in [RFC7400] to signal support for EARO,
as well as the node's capability to act as a 6LR, 6LBR and 6BBR. Section 6.3 defines new flags for the 6CIO to signal support for
EARO, as well as the node's capability to act as a 6LR, 6LBR and
6BBR. Section 7.1.1 specifies how the "E" flag can be used to
provide backward compatibility.
The 6CIO is typically sent in a Router Solicitation (RS) message. The 6CIO is typically sent in a Router Solicitation (RS) message.
