Good job @AnnamalaiRajeev. The only thing I couldn't map from our current configs is the option to enable automatic discovery of a MEP. Is there any other way to represent this in the model? Thanks
Juniper description: "With automatic discovery a MEP is enabled to accept continuity check messages (CCMs) from all remote MEPs of the same maintenance association. If automatic discovery is not enabled, the remote MEPs must be configured. If the remote MEP is not configured, the CCMs from the remote MEP are treated as errors."
@AnnamalaiRajeev follow up comment from last week's operator review:
Please add a leaf for MEP auto-discovery. Because there is not a standard for the default value, then don’t specify a default in yang, rather users must configure explicitly true or false. If unset, then it’s implementation specific.
