Chris , Vikram ,Brian,Shculz and the rest.....

Sorry for the long mail,but have included all possible details...

I have tried what you suggested, i.e to join the R2 ethernet interface
connected to R6 to 228.28.28.28

I tried pinging the 228.28.28.28 address from BB1 and intrstingly i
got replies from all the devices in the domain which had members to
this group.
The output of ping was as follows.

BB1#ping 228.28.28.28

Type escape sequence to abort.
Sending 1, 100-byte ICMP Echos to 228.28.28.28, timeout is 2 seconds:

Reply to request 0 from 132.1.26.2, 84 ms
Reply to request 0 from 132.1.17.7, 172 ms
Reply to request 0 from 132.1.0.3, 128 ms

The show ip mroute on R6 was as follows:

Rack1R6#sh ip mroute

  Outgoing interface list: Null

(54.1.2.254, 228.28.28.28), 00:03:19/00:02:55, flags: T
  Incoming interface: Serial0/0, RPF nbr 0.0.0.0
  Outgoing interface list:
    Ethernet0/0.26, Forward/Sparse, 00:03:19/00:03:06

    Ethernet0/0.6, Forward/Sparse, 00:29:04/00:02:45

I then removed the membership from the interface of R2, and was not
able to get reply at all.
