is 5009 the right choice for me? 1.5 WAN inbound and 10 Gb LAN connection

Hardware MikroTik hardware general
1

setup
<A.ISP> 1.5 Gbp-> <B.cable model> → < C.RB750Gr3 router> → <D. Switch> - > 10 Gb SFP+ devices (main desktop, proxmox cluster, NAS)
<D. Switch> → 1 Gbe ports (Everything else including 3X Unifi AC Pro Wifi AC)

A. cable ISP 1.5 Gb down
B. CM2050V cable modem that can do 2.5 Gbe WAN out
C. Mikrotik RB750gr3 hex router
D Brocade/Rufus ICX 7250 switch (8x SFP+ and 24x 1Gbe)

Goals

  • allow 10 Gb devices to use full ISP speed.

I think I need to upgrade the router with something that would allow >1Gb incoming RJ45 and can connect to the switch over 1Gb speed (i.e. over SFP+)
if RB5009 what I should be looking for?

  • plug WAN into first RJ45 port that is set for 2.5
  • plan LAN into SFP+ and send that into the switch SFP+ port
  • if another backup WAN is created just plug that into another RJ-45 port that would be 1 Gb speed

or should I be looking at something else altogether?
thank you

Hi,

I’ve a similar setup.
5G/1G fiber connection, with a operator box (freebox pop in france) with 2.5G interface, so directly on the eth1.

My lan’s are on the other rb5009 ports, AP are trunked and access mode for the other legaxy parts.
I’m plannng to upgrade the operator by upgrading my offer and change box with a native 10G port and speed around 8G/2G.
So i’ll add a switch, like CRS310 as L2 switching and keep RB5009 as main L3 routers
