Hi,
       How does a PMBR originate a (*,* RP) Join? How many (*,*,RP) entries are created in the PMBR?. 
       
Pl help me in the folowing scenario.

       The following states exist in a router 

        type of Entry           Group Addr         RP Address     iif      oif

         (*,G1)                     235.10.2.1         10.0.14.192     1         2

         (*,*, RP)                 224.0.0.0            10.0.14.192     1       2,3

   Suppose if the router receives a data packet with Mcast Grp Addr = 236.10.12.5. How the packet's Grp Address  is "matched" with   
   the entries present? There can be two possibilities.
             
                From RP-set table in the router,
 
                        1) RP for G (236.10.2.5) can be same as RP address in (*,*, RP) entry. 
 
                        2) RP for G (236.10.2.5) can be different from RP address in (*, *, RP) entry.

   Is the packet forwarded in both the conditions?
                       Looking forward to ur replies , 

Regards,
Subramanian.
