Hi everbody,

I have a problem with 2 mikrotiks, the 2011UiAS and the 3011UiAS.
We have 2 datacenters that is connected with an NDIX, previously we used a sophos UTM to bridge the datacenters but we wanted to lower the load on the Sophos UTM.
So we have placed mikrotiks instead with the routing tables in place, except i`m getting a connection drop every 60 seconds, this problem was not present when using the Sophos UTM.


Router is in bridge mode, I have used the following commands to create the vlans on ether5;
/interface vlan add name=vlan-2667 vlan-id=2667 interface=ether5 disabled=no
/interface bridge add name=br-vlan2667 disabled=no
/interface bridge port add interface=vlan-2667 bridge="br-vlan2667" disabled=no
/interface bridge port add interface=ether5 bridge="br-vlan2667" disabled=no

After that I created the routing table so that the other networks are routed.


I`m using the latest firmware available, also tried the beta without any results.
What could be causing this issue?

You should not add both the interface and the vlan to the bridge.
Also, try turning off the spanning tree function of the bridge.

Removed the bridge..
Problem solved..

Thanks!
