An apparatus includes a memory to store routing information, and a control unit configured to examine routing information stored in the memory for routing information corresponding to one or more destination nodes in a plurality of destination nodes in response to a message requesting routing information for routes between an originating node and the plurality of destination nodes. If routing information for multiple destination nodes in the plurality of destination nodes is stored in the memory, the control unit generates an information element that includes routing information for the multiple destination nodes, and causes a single message that includes the information element to be generated.
