Can you suggest a Hardware Setup?

Hello,
I have the following configuration currently:

Now the idea is to create 2 VLans for Clients 1 and 2 and use one of the ISPs as main line and the other as a backup connection.
Can you suggest hardware? I have to check what exact switches are used and if they aren’t compatible I would need 2 switches as well.
Main thing I am looking for is a router that handles backup lines and Vlan tagging nicely.

Thanks a lot and have a great day.
best,
Johannes

…there are 4 basic questions:

  • what ISP-speeds do you employ on the respective WAN side on your Fritzbox 1 and 2 ?
  • do you need inter-VLAN routing between client sets #1 and #2 ?
  • why 2 switches … are the sets #1 and #2 physically separated (or will one 48port Switch do)?
  • what is the connection speed for each switch provided by the DC?
