I understand what jumbo frames are and the purpose for them. Larger frames with less header data etc. My question is about the best place to use them and where not to use them.
We have some site to site rpelication traffic that is currently set to use jumbo frames. If I allow jumbo frames on the MPLS link. Does that mean that all traffic uses jumbo frames? Does normal workstation traffic that is using standard frames get changed to a jumbo frame before transmit. If not - I am trying to see the con of allowing jumbo frames.
My assumption was that you only allow jumbo frames where it is really needed. If allowing jumbo frames within the network does not impact standard frame traffic - what is the downside of allowing it everywhere ?
Thanks
