here's the config:
R1:
interface FastEthernet0/0
ip address 172.16.80.1 255.255.255.0
ip igmp join-group 229.10.10.10
duplex auto
speed auto
R2:
ip multicast-routing
interface FastEthernet0/0
ip address 172.16.80.2 255.255.255.0
ip pim dense-mode
duplex auto
speed auto
here's the ping:
R2#ping 229.10.10.10 rep 10
Type escape sequence to abort.
Sending 10, 100-byte ICMP Echos to 229.10.10.10, timeout is 2 seconds:

Subject: Re: Router as Multicast Host
I tihnk you'll have to post your configs. ip mulicast routing is not
required for R1 to respond to pings to 229.10.10.10 from R2, in my setup
I can enable just a join on the interface on R1 facing R2, then R2 is
able to ping 229.10.10.10, the only config on R2 is to enable multicast
routing and put pim dende on the interface going towards R1

For this scenario:
R1(join 229.10.10.10)-----------(pim dense)R2(pim
dense)----------------(pim dense)R3
With the setup, R2 can't ping 229.10.10.10
What is the possible solution for this, if R1 can not enable ip
multicast-routing.
Following is the debug from R2:
