At Router_E, Ethernet 2/1 is the incoming interface of the(*, G) entry, and
Ethernet 1/1 is on the outgoing interface list of the(*, G) entry. This means
that there is a group member through Ethernet 1/1, and RP is reachable
through Ethernet 2/1.
The 0 position on this 32-bit index is for Ethernet 1/1(as illustrated in the
interface display above). The j on the 0 index indicates that the Join has come
from Ethernet 1/1.
Since Router_C is the RP, and the root of this multicast tree, the show ip pim
sparse-mode mroute command on Router_C shows RPF nbr as 0.0.0.0 and
RPF idx as none.
