Hi Experts,

This is my topology:-

R3 ,<-----FR------> R5
                                | |
                               | |
                             FR FR
                              | |
                             | |
R6 <----Fa ---> R2 R4

I am using PIM SM on all the Interfaces. I enabled PIm SM-SM on R2 and R6 on
Loopback interfaces so that both of them become RP for the group 224.x.x.x.
Now my query is on R5, when i do show ip mroute 224.0.1.39, I get this
output:-

r5#show ip mroute 224.0.1.39
IP Multicast Routing Table
Flags: D - Dense, S - Sparse, B - Bidir Group, s - SSM Group, C - Connected,
       L - Local, P - Pruned, R - RP-bit set, F - Register flag,
       T - SPT-bit set, J - Join SPT, M - MSDP created entry,
       X - Proxy Join Timer Running, A - Candidate for MSDP Advertisement,
       U - URD, I - Received Source Specific Host Report,
       Z - Multicast Tunnel, z - MDT-data group sender,
       Y - Joined MDT-data group, y - Sending to MDT-data group
Outgoing interface flags: H - Hardware switched, A - Assert winner
 Timers: Uptime/Expires
 Interface state: Interface, Next-Hop or VCD, State/Mode

(*, 224.0.1.39), 00:16:59/stopped, RP 0.0.0.0, flags: DP
  Incoming interface: Null, RPF nbr 0.0.0.0
  Outgoing interface list: Null

(2.2.2.2, 224.0.1.39), 00:00:57/00:02:02, flags: PT
  Incoming interface: Serial0/0.52, RPF nbr 10.1.25.2
  Outgoing interface list: Null

But I am not getting the (S,G) Tree for the Loopback of R6. For R2 I can see
2.2.2.2 but not for R6 which should be 6.6.6.6. I don't know why R5 is not
getting that. This is my first question??

My second question is will R3 also have 2 entries :- one from R2 i.e---
2.2.2.2 and one from R6 i.e--- 6.6.6.6. If yes then I don see anyone of them
on R3. When I do show ip mroute 224.0.1.39 on R3 it says group 224.0.1.39
not found.???

Please can anyone advise....
