Hi
Have a basic Doubt
what is the minimum packet size to transmit ?
I have studied that its 64 bytes ,
but some websites says 68 , is it true ?
also i found the packet size below that value , which is 44 bytes for the EIGRP packet (I did this test in serial interface) , is there any exception for control traffic ?
please Find the attached photo which shows packet with 44 bytes
Thanks in advance.

As peter told frame size must be at least 64 bytes ( which is slot-time of Ethernet to detect the collision ),
so even if the data is not sufficient, device must pad 0s to come up with 64 byte frame. this i could understand.
But if you see my below output Ethernet interface transmits EIGRP packet with 60 bytes , how its possible ?

I think you are right, could you tell me is there any way to confirm it ?
so that I can conclude.

Expand the frame and see if FCS is shown.
