As already stated here: http://forum.mikrotik.com/t/v6-0-released/66371/214
VLANs are not working on x86 platform of v6.
Configuration:
router-os on VMware ESXi v5.0 623860
Single vCPU
2 E1000 NICs (1 without VLAN, 1 with tagged VLAN)
64 MB vRAM
256 MB IDE HDD
Under v5.25 everything works as expected. After upgrade to v6.0 communication over VLAN interface stops working. Communication over “normal” interface without vlans is working normal.
When doing pings from other machine to the VLAN ip adress of router-os i get nor response from it. But I can see packets beeing received and sent on the vlan interface in a number and interval expected for ping receive and response.
I’ve only tested IPv4 not IPv6.
I belief the response frames are misformed so that the switch drops them or just don’t get them as VLAN traffic. Will do more investigation into this later with wireshark.
When doing a downgrade to 5.25 everything is back to normal.
I’ve configured no firewall rules for test purpose. Just naked configuration with two IP adresses an each interface (no VLAN interface and VLAN interface).
/interface vlan
add interface=ether1 name=vlan_netzwerge vlan-id=40
/ip address
add address=192.168.102.254/24 interface=vlan_netzwerge
add address=192.168.222.254/24 interface=ether2
