Network setup that I'm working on for my landlord. Pictured are three Mikrotik RB750Gr3 and one ZyXEL GS1900-24E. I'm considering to reduce the number of cables from each router to the switch to just one, because the RB750Gr3 can only do 2 Gbps across its ports total anyway, and it'll allocate 1 Gbps each to the switched and non-switched ports if switching is enabled. I already collapsed the IPTV and the backbone into two VLANs one port for this reason.
