I'm posting for question about mtu issue.
almost ethernet(fast/gigia/ten-giga...) uses 1500bytes of mtu.
as you know, mtu is a maxium size which router/switch can send for outgoing direction.(or onward)
so mtu is not a thing about receiving data size.
then how much data(bytes) router can receive?
whether data size is 1500 or bigger, router can receive it?
router has fast-ethernet 0/1 and 0/2
both interface mtu size=1500bytes
when 2000bytes data comes from 0/1 and outgoing 0/2
in my mind, router would receive the data well because of mtu=1500bytes has not a releation with receving data size.
after this, router would send the data with 2 packets(1500byte+500byte) to outgoing interface(0/2)
is my guess right?
if it's right, how much bytes router can receive? jumbo size(about 9000bytes)? or something else?
Thanks for reading this post.

One of the best written articles on the Cisco website IMO. Well worth reading and re-reading. Also agree that the foundational understanding this gives you should mean you can answer the query yourself and gain a lot more in the process.
