Abstract
The present application is directed towards systems and methods for using equal cost multi-path routing for traffic distribution in a cluster environment. Each intermediary device of a cluster may advertise, via a routing protocol to a router, a corresponding internet protocol (IP) address of a virtual server and one or more connection metrics having predetermined values. Upon determining that another intermediary device of the cluster is unavailable, each active device may re-advertise the IP address of the virtual server executing on the intermediary device and the one or more connection metrics with the previously advertised value reduced by a predetermined amount. In some embodiments, each active device may wait a predetermined time period, such as a time period for expiration of routing protocol tables, and then re-advertise the IP address of the virtual server executing on the intermediary device and the one or more connection metrics with the predetermined values.
