Hi, I need to run EIGRP. In the beginning, we will just do EIGRP stub routing, so 3750E TD-S is good for us, but later we may reuse the same switch to do full EIGRP routing. My question is if we buy a 3750E-TD-S now, can we upgrade it to 3750E-TD-E for the full EIGRP routing function? Will a software IOS upgrade do that?
I believe you can use the command license boot
I cannot verify it in my lab switch.
Here is a link of the license activation commands and procedures
