i have two router and one switch,all of then connect to the switch.now,when i change the r1 fas0/0 's delay 10000.and ping the ip
of r1's fas0/0 by the r2.the response time is only 23ms.why? i have change the delay is 10000.
there are software based WAN emulators I've used some years ago one from Shunra to emulate a satellite link
you can download a free trial.
it should allow you to emulate delay, packet loss and so on.
You should install it on a PC with two NICs.
Hope to help
