Hi,

    When a Join for Source S is received and the Receiving Router has
     (*,G) Entry oif = Null  and 
     (S,G) Entry oif = Null
     What happens? Or Can this state happen at all?     

    When a Join for RP Wc = Set RPT = Set is received and the Receiving Router has
     (*,G) Entry oif = Null  and 
     (S,G) Entry oif = Null
     iif (*,G)   ! = iif (S,G)
    
    Action : Pl Tell my answer is right

    Make (*,G) & (S,G) State to forwading state.

Output : Send Join twd Source Join 0 0
             Send Join Twd RP, Prune list = Source S (Join  11 + Prune  0 1)
 Am I right?

3) Now for the above shud the SPT bit be cleared if it is set or it wi\ould have been Cleared
    when  (S,G) Entry has Null Oif List.
