Hi, group

    I configure R1, R2, and R3 for IP multicast routing. I can ping
224.10.1.1 and 224.20.1.1 on R3, and ping 224.10.1.1 and 224.30.1.1 on R2,
but I can't ping 224.20.1.1 and 224.30.1.1on R1.

<------ TEST PART ------>
R1:
R1#ping 224.20.1.1

Type escape sequence to abort.
Sending 1, 100-byte ICMP Echos to 224.20.1.1, timeout is 2 seconds:

R1#ping 224.30.1.1

Type escape sequence to abort.
