Hi Sam,
If I change to dense mode, it's working
R1#ping 239.23.23.23
Type escape sequence to abort.
Sending 1, 100-byte ICMP Echos to 239.23.23.23, timeout is 2 seconds:
Reply to request 0 from 162.1.38.8, 376 ms
Reply to request 0 from 162.1.38.8, 412 ms
Reply to request 0 from 162.1.38.8, 380 ms
But what is the meaning if I have three reply response ?
Anybody can explain it to me. Multicast section make me confuse.

I Have Check it, no problem with rpf.
Just to make it clear, rpf is considered okay if the incoming packet
from r1 to sw2 must be go out back with the sam interface right ?

Hi,
Can you check SW2 for any rpf issue to R1 source IP addresss ?

Hi all,
I have a question About Multicast
Topology :
R1-----FRAME RELAY Point to Point ------R3----ethernet---SW2---ethernet
ip igmp join group 239.23.23.23
R3 is the autorp and the mapping agent.
I can do ping from R3 to the group 239.23.23.23
But I cannot ping it from R1 :
R1#sh ip mroute

R1#ping 239.23.23.23
Type escape sequence to abort.
Sending 1, 100-byte ICMP Echos to 239.23.23.23, timeout is 2 seconds:

R1#
R1#mtrace 162.1.13.1 239.23.23.23
Type escape sequence to abort.
Mtrace from 162.1.13.1 to 162.1.13.1 via group 239.23.23.23
From source (?) to destination (?)
Querying full reverse path... * switching to hop-by-hop:
0 162.1.13.1
-1 * * * Timed out receiving responses
Perhaps no local router has a route for source, the receiver is not
a member of the multicast group or the multicast ttl is too low.
Can you guys figure it out why I cannot ping the group address
