Hi ZAVA,

Thanks for writing to this forum. Seeing the given outputs, my rough guess is this device is the RP for the mcast group-239.239.89.44

Also, the the source is directly connected to the device.

Could you please share the below outputs to understand the topology and the mcast traffic flow?

 

#show ip mroute 239.239.89.44 detail

#show ip pim upstream joins 239.239.89.44

#show ip igmp groups 239.239.89.44 detail

#show run int vlan 30

#show ip route 142.222.29.190

#show ip route 142.222.29.1

#show pim ipv4 protocol counters

#show tech-support | no-more
