ASA ECMP static routing

On a Cisco ASA, it is possible to configure up to three equal cost static routes to a particular destination per interface. Equal-cost Multi-path routing (ECMP) is only supported for static routes on the same interface. ECMP is not supported across multiple interfaces.

An example of three equal cost static routes directing traffic to three different gateways on the outside interface can be seen below:
