Network Working Group L. Wang Internet-Draft S. Hares Intended status: Standards Track E. Wu Expires: March 30, 2015 Huawei September 26, 2014 Yang Data model I2RS to IS-IS protocol draft-wang-i2rs-isis-dm-00 Abstract IS-IS is a widely deployed link-state protocol in routing networks. During the past decades, it has been operated and maintained through typical CLI, SNMP and NETCONF. With the expansion and complication of modern networks, the necessity for rapid and dynamic control has been increased. The I2RS is a standard-based interface which provides a programmatic way to achieve this goal. This document specifies a data model for the I2RS's interface to the IS-IS protocol based the I2RS IS-IS informational model (draft-ietf- wu-info-model-00). These two models satisfy the requirements suggested by the I2RS use case requirements for the IGPs. This yang data model can be used by I2RS client-agent protocol to program IS-IS routing entities. Requirements Language The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119].

Introduction IS-IS[ISO.10589.1992] is a widely deployed link-state protocol in routing networks. During the past decades, it has been operated and maintained through typical CLI, SNMP and NETCONF. With the expansion and complication of modern networks, the necessity for rapid and dynamic control has been increased. The I2RS [I-D.ietf-i2rs-architecture] is a standard-based interface which provides a programmatic way to achieve this goal. The draft-wu-i2rs-info-model specifies an I2RS information model (IM) for IS-IS. This I2RS yang data model (DM) that instantiates the information model in a data model. This pair of ISIS IM and DM provides the functional suggested in the requirements for the IGP defined by by [I-D.hares-i2rs-usecase-reqs-summary]. Wang, et al. Expires March 30, 2015 [Page 2] Internet-Draft IS-IS Data model September 2014 In order to support large intra-domain, IS-IS has been organized hierarchically into areas. Routing within an area is referred to as Level 1 routing while routing between areas is referred to as Level 2 routing. Each IS-IS routing system advertises and collects link- state information independently then makes decision in the distributed manner. The outcome of this decision is used to populate Routing Information Base (RIB) since IS-IS can be one of the clients of RIB as stated in [I-D.ietf-i2rs-rib-info-model]. 1.1. Yang Tree Diagrams The Yang Tree diagrams used in this draft utilized a simple graphical representation of the data model. The meaning of the symbols are as follows: o Brackets "[" and "]" enclose list keys o Abbreviations before data node names: "rw" mean configuration (read-write) and "ro" state diagrams. o Symbols after data node names: "?" means an optinal node, "!" means a presence container, and "*" denotes a list and leaf-list. o Parentheses enclose choice and case nodes, and case nodes are also marked with a colon (":"). o Ellipis (". . . ") stand for the contents of subtress that are not shown. Future yang symbols may be added to indicate the object relationship, ephemeral state, and other I2RS specific relationships in yang 1.1 2. IS-IS data Model This section describes the data involved in the IS-IS information model in detail. IS-IS data includes information related to IS-IS instance, IS-IS level, IS-IS multi-topology, IS-IS circuits, IS-IS adjacencies and IS-IS routes. A high-level architecture of the IS-IS contents is shown as below. Wang, et al.
