Look at the following result of extended ping command:
Sending 2, [1500..2000] byte ICMP Echos to 172.16.113.17, timeout is 2
seconds:
Packet has IP options: Total option bytes=39, padded length=40

End of list
Unreachable from 172.16.192.0, maximum MTU 1478 (size 2000)
Received packet has options
Total option bytes= 39, padded length=40
Record route: 0.0.0.0 0.0.0.0 0.0.0.0 0.0.0.0
0.0.0.0 0.0.0.0 0.0.0.0 0.0.0.0 0.0.0.0
My question is: if the path's maximum MTU=1478, how reply to
request 0 (size 1500) exists and how request goes through
routers to the destination?
Thank you.
