RFC 7371 Multicast Flag Bits September 2014
1. Introduction
This document updates the IPv6 addressing architecture [RFC4291] by
redefining reserved bits as generic flag bits (Section 2). The
document also provides some clarifications related to the use of
these flag bits (Section 3).
This document updates [RFC3956], [RFC3306], and [RFC4291]. These
updates are logical consequences of the new processing rules in
Section 3.
