I observed one very strange thing in my setup.I am getting periodic traffic drops while sending traffic to
a particular group ( Traffic is within the threshold limit , 500K ) .Initially everything goes fine and suddenly the source CE receives one prune message for that group and traffic starts decreasing and eventually stops completely ( towards the core) .
After some time source CE again starts forwarding the traffic. I am sending IGMP V1 join from receiver side .
Attached are some Logs I have taken.
