Abstract: In one embodiment, a first label-distribution-protocol (LDP) session is established between a first interface of a first computing device and a second computing device, while a second LDP session is established between a second interface and the second computing device. The method may further comprise receiving a request from a third computing device to subscribe to a multicast group, storing an association between a first label, the multicast group, and the first interface, and sending, to the second computing device via the first LDP session, an indication that the first label is associated with the multicast group. Further, the method may include receiving a request from a fourth computing device to subscribe to the multicast group, storing an association between a second label, the multicast group and, the second interface, and sending, via the second LDP session, an indication that the second label is associated with the multicast group.
