Abstract:
In one embodiment, a method is performed. A device may include an interface in communication with a network. The device may determine whether an all-active multi-homed ethernet segment (ES) associated with the interface is enabled. On a condition that an all-active multi-homed ES is enabled, the device may determine an ethernet virtual private network (EVPN) designated forwarder (DF) state of the all-active multi-homed ES. If the all-active multi-homed ES is enabled and has an ethernet virtual private network (EVPN) designated forwarder (DF) state, the device may enter a protocol independent multicast (PIM) designated router (DR) state. If an all-active multi-homed ES is enabled and does not have an EVPN DF state, the device may enter a PIM non-DR state.
