ecmp

Equal Cost Multipathing (ECMP), for the vSphere admin, is ability to create routes with an equal cost, which allows multiple paths to the same network to be created and traffic can be distributed over those paths. This is good for a couple of reasons - firstly is availability. If we were to lose a host, and an NSX Edge, the route will time out quicker than NSX Edge High Availability - thus providing higher availability for our network traffic.
