Bridge stop work after reboot.

RouterOS General
1

I set up 2 ethernet cards in bridge and everything work fine,but when the system reboot the bridge don’t work.I fix it with “/interface disable bridge1”
“/intreface enable bridge1”.Sometimes bridge stop work when the MT is running.I use Mikrotik 2.9.2.

I have seen this happen with 2.8.xx (I think 26), then when I use 2.8.27/28 it is ok

Try upgrading your RouterOS to 2.9.6 or recreate the bridge.

I have installed 2.9.6 but the problem still exist.Here are my settings:
/ip address add address=10.10.1.1/24 interface=ether1
/ip address add address=10.10.1.2/24 interface=ether2
/interface bridge add disabled=no name=bridge1
/interface bridge port set ether1,ether2 bridge=bridge1
Is there something wrong?

IP addresses should be on the bridge, not on individual interfaces. (You can’t have addresses from the same net on different interfaces).

5

It is not important.I tried without any ip addresses and with ip address on bridge,but there is no change.Is it possible to be hardware problem,because when I disable and enable ether1 after reboot bridge start work?

Did you try with other NICs? Are NICs with the same chipset or different. Sometimes NICs with different chipset crash eachother when they use a share IRQ.

7

Like Eugene says you must have the IP address bound to the bridge and none on the NIC

8

I have already done this but with no success.Any other ideas?

Then it should be a hardware problem.

enable NTP-Client und Netwatch, then the Bridge work after reboot :mrgreen:
