LB ECMP 3 Line ISP Failover - Mikrotik Script RouterOS

LB ECMP 3 Line ISP Failover - Mikrotik Script RouterOS

ECMP or Equal Cost Multi Path is a load balancing method that uses the per address-pair connection load balancing method. ECMP allows a router to have more than one gateway to a destination network. Because the method is per address-pair connection, the load balancing system is that each different address on different connections will probably pass through different gateways.
