Hi all,
I'm watching VoD about Multicast VPN configurations while replicating all the
configs on dynamips.
Everything's fine until a couple of minutes from the end of the video: when I
try to ping 239.7.7.7 from R1 as in the video I get an answer from the first
ping and then nothing:

Is that the right behaviour? Am I wrong expecting subsequent ping answers on R1?
Thanks.
