Hi,

I think GigabitEthernet0/17 and GigabitEthernet0/18 are the uplinks to the router.

you are correct but i do not know why the GigabitEthernet0/17 cannot be routed port but the GigabitEthernet0/18 can.

Did not know that and not sure exactly why that is the case.

maybe Cisco wants to keep the function separate per port.

Hello,

I would also like to understand what are the differences between these ports

I don't find clearly the purpose of each

thanks
