We have an Alcatel Core switch connecting several VLANS togethers. Everything is running fine as we desire, except for the following problem. If I run the trace route (tracert) from a computer to another and these two computers are on the same subnet and connected to the same switch module, in some cases I get a reply from the Gateway not from the other computer. Normally, I should get the answer directly from the other computer in almost no time. But Sometimes I get a reply from the gateway and the reply comes too late (about 50 ms), then second answer come from the other computer in less than 1 ms. What I have to add is that, when I run ping -t the destination address, all the replys comes in less than 1 ms. So please can you guide me what I have to do in order to solve this problem.
