Regarding Multicasting

Hi Experts,

Below is the output of one my router in Lab:

R4#show ip pim interface count | b Address
Address Interface FS Mpackets In/Out
10.1.34.4 Serial0/0.43 * 68/0
10.1.45.4 Serial0/1 * 0/0
4.4.4.4 Loopback0 * 0/0

***************************

(2.2.2.2, 224.1.1.1), 00:01:33/00:01:26, flags: L
  Incoming interface: Null, RPF nbr 10.1.100.3
  Outgoing interface list:
    Serial0/0.43, Forward/Dense, 00:01:35/00:00:00
    Serial0/1, Forward/Dense, 00:01:35/00:00:00
    Loopback0, Forward/Dense, 00:01:35/00:00:00

The topology is:
                               _____ fe link___
                              | |
R2------R1- serial---R3--serial link----R4---- serial--R5------R6

My source is R2 and all the other routers join the group 224.1.1.1

Now the problem is that R4 is receiving the mcast packets from 101.34.3(R3)
but it is not forwarding them out via serial0/1 to R5. Although in the
mroute table i can see the outgoing interface. I have checked the
configuration's and they look good to me. I am not able to identify what is
prompting R4 not to send the mcast packets out via serial 0/1.

I have checked the RPF for the source i.e R2 on R5 and my RPF is good. Did
mtrace also and that also looks good.

Please advise.
