Положу тут рецептик балансировки нагрузки без BGP с failover’ом на Mikrotik’е:

`;; Balancing add chain=prerouting action=mark-connection new-connection-mark=routeKS passthrough=no connection-state=new src-address=192.168.33.0/24 nth=2,1 add chain=prerouting action=mark-routing new-routing-mark=routeKS passthrough=yes src-address=192.168.33.0/24 connection-mark=routeKS add chain=prerouting action=mark-connection new-connection-mark=routeMX passthrough=yes connection-state=new src-address=192.168.33.0/24 add chain=prerouting action=mark-routing new-routing-mark=routeMX passthrough=yes src-address=192.168.33.0/24 connection-mark=routeMX

;; Routing add dst-address=0.0.0.0/0 gateway=(адрес первого шлюза) scope=255 target-scope=10 routing-mark=routeKS add dst-address=0.0.0.0/0 gateway=(адрес второго шлюза) scope=255 target-scope=10 routing-mark=routeMX `Пояснять тут особо нечего.
