A method for configuring a network, and a network configured according to such method, provide resilient, redundant connection to an edge device. The system, while not allowing the edge device to participate in the active topology of the network, chooses the active link from the edge device to the network on the basis of the spanning tree information received by the device, but does not allow it to forward or generate spanning tree information. The method manages the redundant connections of an edge device between a first network and a second network, where the second network is managed according to a spanning tree protocol in which spanning tree configuration messages propagate among switches in the second network. The redundant connections are made via a plurality of ports on the edge device coupled to the second network. The edge device monitors spanning tree configuration messages at least one port of the plurality of ports on the edge device coupled to the second network; selects a port in the plurality of ports on the edge device coupled to the second network as an active port for traffic between the second network and the edge device, in response to the spanning tree configuration messages; and prevent traffic ingressing at any port coupled to the second network from egressing at any port coupled to the second network. The selected active port is the port having a least cost path to a root of the second network according to the spanning tree protocol.
