Appendix A. Companion YANG Model for Non-NMDA Compliant Implementations
The YANG module ietf-sr-topology defined in this document is designed
to be used in conjunction with implementations that support the
Network Management Datastore Architecture (NMDA) defined in
[I-D.ietf-netmod-revised-datastores]. In order to allow
implementations to use the model even in cases when NMDA is not
supported, the following companion module, ietf-sr-topology-state, is
defined as state model, which mirrors the module ietf-sr-topology
defined earlier in this document. However, all data nodes in the
companion module are non-configurable, to represent the applied
configuration or the derived operational states.
The companion module, ietf-sr-topology-state, is redundant and SHOULD
NOT be supported by implementations that support NMDA.
As the structure of the companion module mirrors that of the
coorespinding NMDA model, the YANG tree of the companion module is
not depicted separately.
