Dear Olivier and Junior, Thank you for your prompt responses. Olivier, I am testing a routing scenario and will try to implement your test case with DUT and a switch with static MAC addresses (currently I have only two servers available). I will also try with the TSO LRO settings on the "sending" router as you suggested. Junior, thank your for the presentation. Unfortunately my Brazilian Portugese is zero to none and the youtube translation to English is not perfect, but I got the idea. I will reply when i have results. One more question - is it better to have 2x10Gbps in one lagg (for redundancy and a bit of capacity) towards the network, or to use separate 10Gbps for upstream and for the AS network. I have read somewhere that lagg could cause performance issues. So far I have used lagg on 1Gbps but never on 10Gbps.
