<en_message>This puzzle shows you what happens when there are duplicate MAC addresses. This rarely happens, but it used to happen more often than should be statistically probable. Cheap network card vendors used to make batches of cards with the same MAC address, and occasionally someone would buy two of them. The best solution is to replace one of the NICs that has the duplicate MAC address. Ping both pc0 and pc1 from pc2.</en_message>
