[Xorp-users] querry in pim-sm module file:pim_proto_join_prune_message.cc

Hello friends,

  I have got one querry in pim-smmodulefile
:pim_proto_join_prune_message.cc  of xorp.The querry is located on line
no.s: 246-250. The lines are:
// Remove redundant entries: all (S,G,rpt)J
            while (! jp_group->sg_rpt()->j_list().empty()) {
                const IPvX& addr = *jp_group->sg_rpt()->j_list().begin();
                jp_group->sg_rpt()->j_list_remove(addr);

What does above lines do? Why do not we do it in (*,*,RP) table?

   Thanks in advance for help.
