A routing device may be connected to multiple spoke site networks, and may receive local routes from these spoke site networks. The routing device may include routing information and forwarding information. The routing device may update the routing information to include the local routes, and selectively generate the forwarding information to exclude the local routes. The routing device may associate labels with the local routes and advertise the labels and local routes to other routing devices. The labels may be associated with interfaces of the routing device or access links that connect the routing device to a spoke site network, and the associations of labels with interfaces or access links may be stored in the forwarding information. The routing device may forward received packets that include the labels according to the labels, and may forward other received packets according to the routes within the forwarding information.
