Method of and systems for network redundancy and failure detection are disclosed. A method of assigning runtime states to nodes in a network includes transmitting initial route metric values associated with IP addresses of mobile network nodes to a router system, the relative magnitudes of the metric values being based on primary or secondary node status and active or standby runtime states. The method also includes transmitting packet(s) from one or more mobile network nodes to the router system destined for a server and one or more mobile network nodes receiving a response to the packet transmission via the router system from the server. In response to receiving the response to the transmissions, the one or more mobile network nodes setting subsequent route metric values having a reversed relative magnitude relationship to that of the initial route metric values.
