    description
      "This module describes a YANG model for ISIS protocol configuration.
It is a limited subset of all of the configuration parameters
available in the variety of vendor implementations, hence it is
expected that it would be augmented with vendor - specific configuration
data as needed. Additional modules or submodules to handle other
aspects of ISIS configuration, including policy, routing, types,
LSDB and additional address families are also expected. This model
supports the following ISIS configuration level hierarchy:

ISIS
+-> { global ISIS configuration}
   +-> levels +-> { level config}
       +-> { system-level-counters }
       +-> { level link-state-database}
   +-> interface +-> { interface config }
       +-> { circuit-counters }
       +-> { levels config }
       +-> { level adjacencies }";
