Regarding configuring attributes present in deviation yang file

hi ,

I am trying to configure ISIS from NSO , but it fails saying “area-address” must be configured.
However , ‘area-address’ is part of ISIS-dev-yang and NSO is not considering this deviation yang file.

Can you please suggest any work around or solution for this?

NSO question to a ConfD related forum and not exactly an abundance of information… You probably want to ask such questions on the NSO Developer Hub.

I guess you are referning to the IETF draft ?
If so, just take a look at why the

        must "count(area-address) > 0" {
             "At least one area-address must be configured.";
             "Enforce configuration of at least one area.";
