In this paper, we define the total degree (TD) of a vertex in the join of two interval valued fuzzy graphs (IVFGs) and investigate their totally regular property (TRP). In general, the join of two totally regular IVFGs need not be a totally regular interval valued fuzzy graph (TRIVFG). We obtain some necessary and sufficient conditions for the join of two TRIVFGs to be totally regular.
