1. A method comprising:
receiving, by a switching device, a first join for a Protocol-Independent Multicast (PIM);
creating, in response to receiving the first join, states for the first join for the PIM at the switching device, wherein creating the states at the switching device comprises creating the states for a first protocol mode that is source aware and the states for a second protocol mode that is not source aware;
creating the states for the first join for the PIM at other switching devices between the switching device and a source of PIM, wherein creating the states for the first join at the other switching devices comprises creating the states only for the second protocol mode that is not source aware; and
sending a second join based on the states associated with the second protocol mode.
