SRv6 interoperability report
draft-filsfils-spring-srv6-interop-01
Abstract
Segment Routing (SR) can be applied to the IPv6 data plane by
leveraging a new type of routing extension header, called Segment
Routing Header (SRH). An SRH contains an ordered list, or sequence,
of segments representing topological or service-based instructions,
or any combination of those.
This draft provides an overview of IPv6 Segment Routing (SRv6)
implementations and interoperability. It makes an inventory of the
various pieces of hardware and software that have been demonstrated
to support the processing of an SRH, and details some
interoperability scenarios that have been showcased at a public
event.

1. Introduction
Segment Routing (SR), defined in [RFC8402], allows a node to steer
packets through a controlled sequence of instructions, called
segments, by prepending an SR header to the packets. The IPv6
instantiation of Segment Routing (SRv6) leverages the Segment Routing
Header (SRH), a new type of IPv6 routing extension header defined in
[I-D.ietf-6man-segment-routing-header].
As described in [I-D.filsfils-spring-srv6-network-programming], an
SRv6 segment is a network instruction composed of a locator and a
