Hi,

I have many some problems in PIM sparse mode , The PIM sparse-mode
setup is some what as below:
                                                                  
Fa0/1
                                                                       |
                                                                     SW
                                                                        |
                                                                      R1
                                                                        |
 BB1 --FR-- R6 ---Ethernet0/0.26(Subif)--- R2 ---- FR
                    | |
               Ethernet0/0.6 R3
---- Ethernet0/0---
                                                                        |
                                                                 Ethernet 0/1
                                                                        |

I have joined interface Fa0/1 on SW, Interface E0/0 & E0/1 on R3 to
228.28.28.28 .

When i ping 228.28.28.28 from R6 i get a reply. But when I do the ping
from BB1 i do not get a reply. R2's Loopback 150.1.2.2 is configured
as RP manually.

R1,R2 ,R3 are able to ping the 228.28.28.28 group without any problems.

The Sh ip mroute on R6 and BB1 as soon as I ping 228.28.28.28 from BB1
 is as follows:

BB1#sh ip mroute
IP Multicast Routing Table

(*, 224.0.1.40), 01:09:47/00:00:00, RP 150.1.2.2, flags: SJCL
  Incoming interface: Serial0, RPF nbr 54.1.2.6
  Outgoing interface list:
    Serial0, 54.1.2.254, Forward/Sparse, 00:26:47/00:02:18

(*, 228.28.28.28), 00:03:32/00:02:26, RP 150.1.2.2, flags: SP
  Incoming interface: Serial0, RPF nbr 54.1.2.6
  Outgoing interface list: Null

Rack1R6#sh ip mroute
IP Multicast Routing Table

(*, 228.28.28.28), 00:08:07/stopped, RP 150.1.2.2, flags: SPF
  Incoming interface: Ethernet0/0.26, RPF nbr 132.1.26.2
  Outgoing interface list: Null

(54.1.2.254, 228.28.28.28), 00:00:30/00:02:38, flags: PT
  Incoming interface: Serial0/0, RPF nbr 0.0.0.0
  Outgoing interface list: Null

(*, 224.0.1.40), 04:01:59/00:02:53, RP 150.1.2.2, flags: SJCL
  Incoming interface: Ethernet0/0.26, RPF nbr 132.1.26.2
  Outgoing interface list:
    Serial0/0, 54.1.2.254, Forward/Sparse, 00:28:12/00:03:05
    Ethernet0/0.6, Forward/Sparse, 04:02:00/00:02:48

In the above output, i notice that the (54.1.2.254, 228.28.28.28)
entry does not have an RPF, this is something i doubt. Any feedbacks?

Any help would be appreciated. I am doin the IEWB Ver3.0 Lab 2 , Task 6
