Hello, I have box connected to 2 isp, via 1.1.1.1 eth0 and via 2.2.2.2 eth1. I want that gateway 2.2.2.2 will be used only if 1.1.1.1 is not active. Curently configuration is with weight 1 and weight 256, so it uses gateway 2.2.2.2 sometimes. I missed some manual topic or it is only way to make backup with iproute2?
