Does anyone here know how to setup a dual gateway network?

Router-1 connects to the internet via ISP-1

Router-2 connects to the internet via ISP-2

Both the routers are in the same building. Obviously, the server system can only remain connected to one router. I'd like to set up the network in such a way that:

-All systems connected to both the routers can communicate with each other and of course the server.

-If the internet connectivity from one router goes down, all the nodes in the network must automatically use the other ISP.

    Load balancing Routers?

    But, do you want to balance traffic or just a fallback?
    A simple spanning-tree on the 2 exit ports haa worked well for me in the past. Just fine tune and test both priorities and costs, and go with rapid-pvst.

    @bigus-dickus the simplest thing I can think of would be an EdgeRouter X from Ubiquity. Costs like 50 Dollars and can do load balancing and all sort of stuff like vpn and stuff. Or you could build your own router running pfSense

    ++ for EdgeRouter X

    Either you set up load balancing or you set up 2 separate DHCP subnets with each of his own gateway and proper routing tables on the gateways for outgoing & subnet to subnet routing.

    I just bought this one :
    TP-Link TL-R470T + Load Balance Broadband Router

    It has yet to arrive. Even if it does, I have no freaking idea how to set it up.

    Thank y'all for your responses!

    @bigus-dickus I was only looking at them so that I could load balance my internet connection.
