A system comprising: a bit indexed explicit replication, BIER, network device; a BIER proxy device; a first network device, wherein the first network device is a non-BIER network device; and one or more other BIER-enabled network devices; wherein the BIER network device, comprises: one or more memories; and one or more processors to: receive information indicating that the BIER proxy device is a BIER proxy for the first network device; and transmit, to the BIER proxy device and based on receiving the information, a BIER-encapsulated multicast packet via a first tunnel between the BIER network device and the BIER proxy device, wherein the BIER-encapsulated multicast packet is to cause the BIER proxy device to generate a plurality of copies of the BIER-encapsulated multicast packet, to add an additional encapsulation layer to each copy of the plurality of copies of the BIER-encapsulated multicast packet when generating the plurality of copies of the BIER-encapsulated multicast packet and to transmit (108-1, 108-i), via a second tunnel through the first network device, the plurality of copies of the BIER-encapsulated multicast packet to the one or more other BIER-enabled network devices. a bit indexed explicit replication, BIER, network device; a BIER proxy device; a first network device, wherein the first network device is a non-BIER network device; and one or more other BIER-enabled network devices; wherein the BIER network device, comprises: one or more memories; and one or more processors to: receive information indicating that the BIER proxy device is a BIER proxy for the first network device; and transmit, to the BIER proxy device and based on receiving the information, a BIER-encapsulated multicast packet via a first tunnel between the BIER network device and the BIER proxy device, wherein the BIER-encapsulated multicast packet is to cause the BIER proxy device to generate a plurality of copies of the BIER-encapsulated multicast packet, to add an additional encapsulation layer to each copy of the plurality of copies of the BIER-encapsulated multicast packet when generating the plurality of copies of the BIER-encapsulated multicast packet and to transmit (108-1, 108-i), via a second tunnel through the first network device, the plurality of copies of the BIER-encapsulated multicast packet to the one or more other BIER-enabled network devices. one or more memories; and one or more processors to: receive information indicating that the BIER proxy device is a BIER proxy for the first network device; and transmit, to the BIER proxy device and based on receiving the information, a BIER-encapsulated multicast packet via a first tunnel between the BIER network device and the BIER proxy device, wherein the BIER-encapsulated multicast packet is to cause the BIER proxy device to generate a plurality of copies of the BIER-encapsulated multicast packet, to add an additional encapsulation layer to each copy of the plurality of copies of the BIER-encapsulated multicast packet when generating the plurality of copies of the BIER-encapsulated multicast packet and to transmit (108-1, 108-i), via a second tunnel through the first network device, the plurality of copies of the BIER-encapsulated multicast packet to the one or more other BIER-enabled network devices. receive information indicating that the BIER proxy device is a BIER proxy for the first network device; and transmit, to the BIER proxy device and based on receiving the information, a BIER-encapsulated multicast packet via a first tunnel between the BIER network device and the BIER proxy device, wherein the BIER-encapsulated multicast packet is to cause the BIER proxy device to generate a plurality of copies of the BIER-encapsulated multicast packet, to add an additional encapsulation layer to each copy of the plurality of copies of the BIER-encapsulated multicast packet when generating the plurality of copies of the BIER-encapsulated multicast packet and to transmit (108-1, 108-i), via a second tunnel through the first network device, the plurality of copies of the BIER-encapsulated multicast packet to the one or more other BIER-enabled network devices.
