A device communicates with feature peers, associated with a network, to obtain information associated with the feature peers, and receives a customer packet. The device also determines, based on the feature peer information, which of the feature peers support a feature associated with the customer packet, and selects, from the determined feature peers, a set of feature peers for the customer packet to traverse. The device further associates, with the customer packet, an additional packet used for delivering the feature associated with the customer packet, and forwards the customer packet and the additional packet to one of the feature peers in the selected set of feature peers.
