Reply for seq 1, return code: Egress-ok, time: 0.551 ms <<<<< is this the round trip time
Yes this is round trip time , You are getting the Echo reply from the egress with the code:Egress ok and the corresponding round trip time to get back the reply for the request
Local transmit time: 2016-09-27 11:38:52 MST 649.261 ms
Local transmit time is the timestamp at which you initiated the echo request from the terminal
Remote receive time: 2016-09-27 11:38:52 MST 649.812 ms
Remote receive time is the timestamp at which you receive the (echo)reply back from remote end (egress) at the terminal .
The difference is the round trip time.
