Problem:
I had three 2.9 routers, I was bridging three LANs. LANs were using VLANs on both sides, and one of them VLANs is used for management.
I had this nice bridge that connected all three, and on this nice bridge I had VLAN interface, that had the VID of management VLAN and was created with bridge as parent interface. Everything worked great.
Well, all things come to an end - I stupidly decided to upgrade to 3.0rc1 hoping for better wireless throughput and stuff. Well, wireless is the same at best, and also my great awesome superb brilliant vlan-on-the-bridge configuration is not working anymore, /ip address print shows 'I' for every IP on vlan interface.
So, what gives? Any way to fix this without using /system downgrade?
Re: VLAN on bridge problem
strangely enough, doing enable on VLAN interface fixed the problem. Any ideas as to why they got disabled (well, there wasn't X along the vlan, but neither was R...) on one router and not on the other?
Also, MACs where changed on NICs and after upgrade they were forgotten and NICs redetected as ether1 and kicked out of bridge. Maybe it's something to look at as bug?

Re: VLAN on bridge problem
If you found any issue at 3.0rc1, that is seems incorrect for you. You must contact MikroTik support (support@mikrotik.com) with attached support output file (that is generated when the problem occurs) and problem description.
Re: VLAN on bridge problem
It seems that after disabling and enabling bridge, vlans are brought into some strange state between disabled and running - there is no 'X' indicator, and there is no 'R' indicator - doing enable on each vlan brings them back to life.
Re: VLAN on bridge problem
Write commands step by step, that causing strange state for the bridged interfaces.
As I have bridge with two VLAN interfaces (related to Ethernet interfaces),
[admin@MikroTik] /interface bridge port> print
Flags: X - disabled, I - inactive, D - dynamic
# INTERFACE BRIDGE PRIORITY PATH-COST
0 vlan1 bridge1 0x80 10
1 vlan2 bridge1 0x80 10
interface print
6 R vlan1 vlan 1500
7 R vlan2 vlan 1500
Disabling/enabling bridge interface does not cause any issues.

Re: VLAN on bridge problem
I'll poke around and see if I can figure out something with 100% breakage ratio.

Done poking around. Changing protocol-mode doesn't enable vlans.
Also, the vlans aren't supposed to be in bridge, but on bridge.
100% success ratio on my tests.

Re: VLAN on bridge problem
Well,
interface bridge set 0 disabled=yes
interface bridge set 0 protocol-mode=rstp
interface bridge set 0 disabled=no
interface bridge set 0 protocol-mode=none
None of this commands does not disable VLAN.

Re: VLAN on bridge problem
Were you able to confirm the problem? What about ethernet NICs with changed MAC-address being forgotten after upgrade from 2.9 to 3.0?
