Internet Engineering Task Force (IETF) J. Haas Request for Comments: 8242 Juniper Category: Informational S. Hares ISSN: 2070-1721 Huawei September 2017 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.

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.
