Right, schema-mount can be used in some cases (logical device or in a VRF) but doesn’t have to be used in other cases (e.g. network device which doesn't support VRFs). We will clarify the text, at a certain time we incorrectly thought that schema mount had to be used in all cases.

Regards,
Reshad.

    This is what I thought but the text is kind of misleading:
    
       BFD can operate in the following contexts:
    
       [...]
    
       The approach taken is to do a schema-mount (see Schema Mount
       [I-D.ietf-netmod-schema-mount]) of the BFD model in the appropriate
       locations.
