Abstract
An example network device includes memory configured to store packet data and processor circuitry coupled to the memory. The processing circuitry is configured to determine that a first host device has moved from a first access network of an Ethernet virtual private network (EVPN) associated with the first PE router to a second access network of the EVPN, wherein the first host device is interested in receiving traffic of a first multicast group. The processing circuitry is configured to determine whether any other host device on the first access network of the network device is interested in receiving traffic of the first multicast group. Based on no other host device on the first access network of the network device being interested in receiving multicast traffic of the first multicast group, the processing circuitry is configured to delete state associated with the first multicast group.
