I want to understand something about best practise with MTU. If you have a server connected in a network and enable jumbo frames between all the places that access that server, then obviously you get a higher MTU and transmission speed across the network. However, most web servers somewhere in the internet will be in a transit path that hits a standard 1500 MTU. Thus, somewhere in the transit path the packets will be fragmented down the a 1500 size packet when the servers access the internet. Let's say that this point is your edge router connecting to your ISP, which will be burdened with this task which gets worse with the more servers configured this way with jumbo frames.
My question is, how do you optimise your internal access between servers (i.e. use jumbo frames here), whilst not burdening your edge router with the fragmentation when the servers use the internet?
