1.  Overview

   YANG [RFC6020] [RFC7950] is a data definition language used to define
   the contents of a conceptual data store that allows networked devices
   to be managed using NETCONF [RFC6241].  YANG is proving relevant
   beyond its initial confines, as bindings to other interfaces (e.g.,
   ReST) and encodings other than XML (e.g., JSON) are being defined.
   Furthermore, YANG data models can be used as the basis for
   implementation of other interfaces, such as CLI and programmatic
   APIs.

   This document defines YANG data modules augmenting the IETF IS-IS
   YANG model [I-D.ietf-isis-yang-isis-cfg], which itself augments
   [RFC8349], to provide support for configuration and operational state
   for the following IS-IS features:

   RFC7987:  IS-IS Minimum Remaining Lifetime[RFC7987].

   The augmentations defined in this document requires support for the
   IS-IS base model[I-D.ietf-isis-yang-isis-cfg] which defines basic IS-
   IS configuration and state.  The IS-IS YANG model augments the ietf-
   routing YANG model defined in [RFC8022].

1.1.  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 [RFC2119].

2.  YANG Module for IS-IS Minimum Remaining Lifetime

   This document defines a YANG module for IS-IS Minimum Remaining
   Lifetime as defined in [RFC7987].  It is an augmentation of the IS-IS
   base model.
