This paper considers the edge-connectivity and restricted edge-connectivityof replacement product graphs, gives some bounds on edge-connectivity andrestricted edge-connectivity of replacement product graphs and determines theexact values for some special graphs. In particular, the authors furtherconfirm that under certain conditions, the replacement product of two Cayleygraphs is also a Cayley graph, and give a necessary and sufficient conditionfor such Cayley graphs to have maximum restricted edge-connectivity. Based onthese results, the authors construct a Cayley graph with degree $d$ whoserestricted edge-connectivity is equal to $d+s$ for given odd integer $d$ andinteger $s$ with $d \geqslant 5$ and $1\leqslant s\leqslant d-3$, which answersa problem proposed ten years ago.
