Going through the early readings for my CCENT and read about these two protocols.

 

I noticed their behavior is very similar, but I think I see a difference between the two when you look at how routers handle the different frames...

 

It's the source (src) and destination (dst) of the frame. I think I'm seeing that Ethernet updates that info with the router's sending interface's (if's) IP for the new src, and the next hop's receiving if's address for the dst.

 

HDLC looks like it maintains the original src and dst from the very first frame sent; from end node to default gateway and so forth.

 

Can anyone confirm this?

 

..am i doing this right? <=D
