Regarding auto-rp in pim sparse-dense mode

Hi experts,
My topology is something like this:-

R5 <---FR----.> R2<---Fa0/0-----Fa0/0----> R6

Now lets say i select R2 and R6 to be configured as the RP's for the group
224.1.1.1 and i configure this on both of them

ip pim send-rp-announce lo0 scope 4 group-list 1 interval 30
access-list 1 permit 224.1.1.1

so now my question is that on R5 if i do :---> show ip mroute 224.1.1.1, it
shows only 1 group which is (2.2.2.2, 224.1.1.1) which is from R2 but not
the other one which is R6( 6.6.6.6, 224.1.1.1)

If I check on R2, I can see both the Groups.I couldn't figure out what could
be wrong??

Is there something that I am missing. Please advise

BTW Pim sparse-dense mode is configured on all the interface's.
