Interface to the Routing System (I2RS) Ephemeral State Requirements
Abstract
"An Architecture for the Interface to the Routing System" (RFC 7921)
abstractly describes a number of requirements for ephemeral state (in
terms of capabilities and behaviors) that any protocol suite
attempting to meet the needs of the Interface to the Routing System
(I2RS) protocol has to provide. This document describes, in detail,
requirements for ephemeral state for those implementing the I2RS
protocol.

RFC 8242 I2RS Ephemeral State Requirements September 2017
1. Introduction
The Interface to the Routing System (I2RS) Working Group (WG) is
chartered with providing architecture and mechanisms to inject into
and retrieve information from the routing system. The I2RS
Architecture document [RFC7921] abstractly documents a number of
requirements for implementing the I2RS and defines ephemeral state as
"state that does not survive the reboot of a routing device or the
reboot of the software handling the I2RS software on a routing
device" (see Section 1.1 of [RFC7921]). Section 2 of this document
describes the specific requirements that the I2RS WG has identified
based on the I2RS architecture's abstract requirements. The
