Abstract
In an embodiment of the invention, a method for providing a router redundancy in a network, includes: monitoring a primary router for a failure event; and selecting a fail-over router to assume the role of the primary router if the failure event occurs in the primary router. The fail-over router is selected and configured by the use of a Router Redundancy Protocol (RRP) application software in a computer.
