Abstract: A method for communication includes configuring a router to forward data packets in a network in accordance with MPLS labels appended to the packets. A group of two or more of the interfaces is defined as a multi-path routing group in a forwarding table within the router. A plurality of records are stored in an ILM in the router, corresponding to different, respective label IDs, all pointing to the set of the entries in the forwarding table that belong to the multi-path routing group. Upon receiving in the router an incoming data packet having a label ID corresponding to any given record in the plurality, one of the interfaces in the group is selected, responsively to the given record and to the set of the entries in the forwarding table to which the given record points, for forwarding the incoming data packet without changing the label ID.
