Hi Reshad, Why do we need a new YANG model for clients? Why can’t they just use ietf-bfd-types.yang? I’d like to avoid the unnecessary levels of indirection. In fact, it looks wrong to me since the grouping bfd-client-ext-cfg-parms uses the grouping bfd-grouping-base-cfg-parms which only contains the enabled leaf. I believe you meant to use bfd-grouping-common-cfg-parms in the other new model. However, I don’t see any reason why client shouldn’t use this directly.
