Interruptions between a source in a first network and a destination in a second network are reduced by providing first primary and secondary nodes in the first network, and second primary and secondary nodes in the second network. First primary routes in the first network facilitate delivery of a first set of the data to the first primary node; and a second set of the data to the first secondary node. Inter-network routes between the first and second networks deliver the first and second sets of the data to the second primary node and the second secondary node. Second primary routes in the second network facilitate delivery of at least one of the first and second sets of data to the destination. A selector within the second network selects one of the sets of data. Route selectors select secondary routes in the event that a primary route is disabled.
