Dear everyone,
In the prune-list processing part of PIM-SM draft says that,
(sec 3.2.2)

1. For each address, Sp, in the prune list whose RPT-bit and
   WC-bit are cleared:

     1. ... (able to understand)

     2. If the router has a current (*,G), or (*,*,RP), route
        entry, and if the existing (Sp,G) entry has its RPT-bit
        flag set to 1, then this (Sp,G)RPT-bit entry is maintained
        (not deleted) even if its outgoing interface list is null.

I am not able to understand the details given the second subsection.

can someone help to understand?

with regards,
bhavesh
