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 }"; revision 2022-05-10 { description "Modify internal/external route preference to unrestricted uint32 type."; reference "1.0.0"; } revision 2022-03-01 { description "Add simple authentication key support."; reference "0.9.0"; } revision 2022-02-24 { description "Add Hello PDU padding type to IS-IS global configuration."; reference "0.8.0"; } revision 2022-01-19 { description "Align revisions across modules."; reference "0.7.1"; } revision 2021-12-31 { description "Add support for per-interface hello authentication, and per-level *SNP authentication."; reference "0.7.0"; } revision 2021-06-16 { description "Remove trailing whitespace"; reference "0.6.2"; } revision 2021-03-17 { description "Add bfd support without augmentation."; reference "0.6.1"; } revision 2020-03-24 { description "Support IGP-LDP sync per interface."; reference "0.6.0"; } revision 2020-02-04 { description "Consistent prefix for openconfig-mpls-types."; reference "0.5.0"; } revision 2018-11-21 { description "Add OpenConfig module metadata extensions."; reference "0.4.2"; } revision 2018-06-05 { description "Fix bugs in when statements."; reference "0.4.1"; } revision 2018-06-05 { description "Fix bugs in when statements."; reference "0.4.1"; } revision 2018-05-14 { description "Update LSDB model to correct Extended IS reach TLV bug.
