IPv6 Router Advertisement Flags Option
RFC 5175, “IPv6 Router Advertisement Flags Option”, is a Proposed Standard document published in March 2008 by B. Haberman, R. Hinden. It obsoletes RFC 5075. The canonical text is published by the RFC Editor.
Abstract
The IPv6 Neighbor Discovery's Router Advertisement message contains an 8-bit field reserved for single-bit flags. Several protocols have reserved flags in this field and others are preparing to reserve a sufficient number of flags to exhaust the field. This document defines an option to the Router Advertisement message that expands the number of flag bits available. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
