I recently brought RB750Gr3. This is my first MT router and don’t know much about its setup, I want to do following setup can anyone help me with that?
It’s probably possible, but it’s mostly general statement based on RouterOS flexibility. There’s so much info missing… you get some points for image, but zero for explanation. I have some idea what you might want, but there’s no point playing a guessing game. Try to add as much info as possible (about both internet connections, both switches, your exact goals and everything).
You could use vlans for this if those are managed switches supporting vlans:
Connect your ISP1 as untagged to a port on the first switch and use the fiberlink as a trunk.
On the second switch do the reverse.
But since your RB750 is already connected, you could use the same physical interface to transport 49.118.4.116 as VLAN and untag it in the router as a VLAN interface (unless you have a good reason to use 2 ethernet interfaces, e.g. you have 10G fiberlink and need the speed). Second variant also allows the second switch to be a dumb switch.
