Bridge mode in LAN problem

Hello,

I have a major in LAN router as RB2011UiAS-2HnD-IN and 2pc RB951G 2HnD-in bridge mode (WISP AP) AP as well as used as a switch to another network segment.

The first bridge works without problems, but the second set identically wants to route, or it can ping.

Anything that’ll put into port 2 and writes an error message:

bridge port received packet with own address as source address probably loop

(see. image) and communication with MK stops working until not block the port (eth2), another port (eth3) works without problems.

Can you think of anything?

export your configuration and post it here…
