Network Working Group L. Wang Internet-Draft S. Hares Intended status: Standards Track N. Wu Expires: March 30, 2015 Huawei September 26, 2014 Yang Data model for I2RS interface to the OSPF protocol draft-wang-i2rs-ospf-dm-00 Abstract OSPF (OSPFv2 and OSPFv3) is 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 an OSPF yang data model for the I2RS interface to OSPF. This model is based on the the I2RS OSPF informational model (draft-ietf-wu-ospf-info-model-00) which satisfies 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 OSPF 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 As one of well-known link-state protocols, OSPF[RFC2328] has been widely used in the routing of intra domain networks. During the past decades, it has been deployed with the help of typical interfaces such as CLI, SNMP and NETCONF. As modern networks grow in scale and complexity, 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. This document specifies an yang data model for I2RS interface to the OSPF protocol based on the I2RS information model specified in draft- ietf-wu-ospf-info-model-00. In order to support large intra-domain, OSPF has been organized hierarchically into areas. The topology of one area is hidden from the rest of networks, which is beneficial from the reduction of Wang, et al. Expires March 30, 2015 [Page 2] Internet-Draft OSPF I2RS DM September 2014 routing traffic. Based on flooding mechanism, each routing-system in one OSPF area will maintain the identical database from which a pair- wise shortest tree is calculated in the distributed manner. As one client of RIB, OSPF SHOULD populate its routing information into 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. OSPF data This section describes the data involved in the OSPF information model in detail. Please note OSPF in this document means both OSPFv2 and OSPFv3[RFC5340]protocol unless specified. OSPF data includes information related to OSPF instance, OSPF area, OSPF multi-topology, OSPF interfaces, OSPF adjacencies and OSPF routes. A high-level architecture of the OSPF contents is shown as below. Wang, et al.
