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].

1. 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].

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.
