Hi.
I have two identical routerboards with the same hardware configuration.
It means one iface is my connection to internet, and 3 interfaces are connected to 3 other microtiks....
I joined these 3 internal interfaces to one bridge(ver. 2.9.11), and I gave 1 IP address to the bridge.
everything is working well, I'm able to ping every IP which is connected to this router(also from router).
the second routerboard has version 2.9.12. When I joined 3 interfaces of second router, and I set an ip address to the bridge(the method was exactly the same as in first case), I'm not able to ping from router the connected IP addresses...
It seems that the bridge is not working in the same way as in first router....
