Abstract
Examples include determining a first hop for a preferred route from a networking device to a destination device, calculating a cumulative cost for the preferred route based on a cost of the first hop and an original cost of the preferred route, determining whether a secondary route is available, and, in response to a determination that the secondary route is available, determining a first hop in the secondary route. Examples also include determining a cost of the first hop in the secondary route, determining a new route from the networking device to the destination computing device based on the cumulative cost of the preferred route and the cost of the first hop in the secondary route, and entering the new route into a forwarding data structure of the networking device.
