Claim One:
1. A method of providing dynamic link redundancy configuration in a data network, comprising the steps of: detecting a topology of a data network; determining a number of data paths from a node in the data network topology to each of a respective pair of peer nodes coupled to the node by a corresponding interface; determining a data path in the data network topology between the peer nodes; calculating a set of nodes reachable via each interface coupled to the node and the respective peer node in the data network topology, without traversing an enabled redundant link pair in the data network topology; comparing the set of calculated nodes reachable via each interface; based on identities of the set of calculated nodes reachable via each interface being the same, concluding that there is symmetrical reachability via each interface of the pair of interfaces; and in response to concluding that there is symmetrical reachability via each interface of the pair of interfaces, configuring the pair of interfaces as a redundant link pair for the node.
