I just started taking CCNA Labs with David Bombal on Udemy and really, it should come with a disclaimer which says not for total beginners.
In the Topology:
PC1 ---------- SW1 ------------ R1 ------------ PC2
In one of his labs where we do a Packet Tracer PING Test from PC1 to PC2, we explore the Inbound and Outbound PDUs and both the Inbound Destination MAC Address and Outbound Destination MAC Address are the same -- they are both R!'s MAC Address. I was wondering, is this correct; am I misunderstanding what a PDU is?
I would have presumed that the for the Outbound PDU the Destination MAC would have been R1's Interface MAC Address and the Inbound PDU's Destination MAC would have been PC1's Interface MAC? Why is this not the case?
