Is the router connected with the switch(mikrotik) or the switch it self is = the gateway ? And can you try pinging IPv6 link-local addresses to each others (although = it should not matter)? Can you share some tcpdump captures while pinging? While I'd suggest you connect two of the three nodes with twisted pair and = this is a minimal setup to narrow down the problem. --=20 You are receiving this mail because: You are the assignee for the bug.=
