MACsec bounded delay protection (MX10003 routers)—Starting in Junos OS Release 21.1R1, you can configure bounded delay protection on MX10003 routers. MACsec bounded delay protection prevents the delivery of a frame when the frame is delayed by two seconds or longer. This feature enables the detection of delayed MACsec frames that result from a man-in-the-middle attack.
