[c-nsp] Pim multicast problem

[Sergey Velikanov [Intelsoft]]

:) I've kill all day for understanding this problem, as soon as I writt to this list,
I've found solution.

problem was that Source1 was reachable via routing, as soon as I add ip of source as secondary ip on vlan151,

mroute changed to

   #sh ip mroute 224.1.1.3
   (*, 224.1.1.3), 01:41:14/stopped, RP 192.168.9.1, flags: SPF <---------- Added F flag
      Incoming interface: Vlan999, RPF nbr R2_ip_addr
      ....

and R1 stats send register message, but could anybody explain why R1 send PIM register only if source directly connected ?
