Hi Shamin,
if the 'ip igmp access-group' is configured on R1 e0/0, I would configure
the 'ip igmp join-group 225.25.25.25' on a router directly connected to R1
e0/0, let's say R4 e0/0. This is how I labbed it and it seems to work.
R4:
ip multicast-routing
!
interface FastEthernet0/0
ip pim sparse-mode
ip igmp join-group 225.25.25.25
then on R1:
r1#show debugging
IP multicast:
IGMP debugging is on
r1#
*Mar 1 07:02:41.979: IGMP(0): Received v2 Query on FastEthernet0/0 from
155.1.146.1
*Mar 1 07:02:41.979: IGMP(0): Set report delay time to 2.4 seconds for

155.1.146.1 for 225.25.25.25
