A routing apparatus includes interconnected switches and a server. At least some of the switches connect to routers belonging to multiple subnetworks, and at least a given switch is configured to receive a packet destined to a subnetwork reachable via the given switch, and forward the packet using forwarding logic of the given switch that supports only a partial subset of the subnetworks, and to monitor traffic flow via the given switch and report traffic flow information indicative of a given subnetwork that is unreachable via the given switch. The server is coupled to the switches, and is configured to receive the traffic flow information from the given switch, and determine switch forwarding information for the given subnetwork, based on the traffic flow information, and to download the switch forwarding information to the given switch, for enabling the forwarding logic to forward subsequent packets destined to the given subnetwork.
