Technical Summary
The data plane for Segment Routing over IPv6 (SRv6) is built using
IPv6 as the underlying forwarding plane. Due to this underlying use
of IPv6, Segment Identifiers (SIDs) used by SRv6 can resemble IPv6
addresses and behave like them while exhibiting slightly different
behaviors in some situations. This document explores the
characteristics of SRv6 SIDs and to clarify the relationship of SRv6
SIDs to the IPv6 Addressing Architecture.
