Hello all,
Please accept my apologies about my questions, I guess that it will be funny, but I need advice.
I have these topology: LAN-Switch---Mikrotik---( )---Mikrotik-Switch non Mikrotik /POE/-IPC1, IPC2, IPC3
IPC3 transmit video signal, IPC1 and IPC2 had problem with transmitting video signal - I tried to lower MTU, and now IPC1, transmit traffic, but IPC2 can't receive video traffic.
Wireless signal works on 5 GHz-A/N 20/40 MHz XX.
Problems are:
Accessing web page on all IPC cameras - very slow.
There is a bridge loop error on bridge1: tx loop on interface (1)
at the same time ping response was almost 2-5 ms, sometimes 16-20 ms.

I need: IPC1, IPC2, IPC3 to be accessed with IP addresses which was set already. both Mikrotik devices had also ip addresses.
Traffic from IPC's was received by video recording server. currently IPC1, IPC3 worked, but IPC2 not worked with recording server.
Could you advice me how to proceed, and also good manual about configuration, because on both Mikrotik router board had configured bridge interfaces.

Any ideas and advices will be help for me.
Thank you.
