While ping is working fine between two VM's these errors are raising false alarms to me. Seems like a problem to me. If something to be fixed I can contribute to fix these errors. Those counters are simply counting packets in the l2fib. You will get same output if you do “show counters”. nothing to worry about. Still I agree that this is confusing and that we might consider separating error counters from the normal ones...
