Good day,
I have setting up a failover between three Mikrotik routers. Router1 is the main router where the internet comes into the environment and the other two routers are connected to Router1. They're all communicating with each other as their's no firewall NAT rules in place.
Each of the routers are installed in different buildings, have their own set up servers and pc and run independently from each other.
Router1 = Main Building
Router2 = Building2
Router3= Building3
I need to setup a failover, so that if the connection between Main Building (Router1) and Building 2 (Router2) breaks for whatever reason, the traffic to Building1 should be routed via Router3 as a failover and vice versa. Is this possible, and if so, what type of config will I need in order to achieve this? There is a link between Router2 and Router3, which can be connected to another eth port.
I did look up on how failover on Mikrotik works, but nothing I can find on the internet explains my type of situation, where most instructions talk routing to a different ISP using masquerade rules and so on.
I want to share my current configs, but not sure how to export it into a readable format for the forum
Thanks for any help or insight in advance.
