we're having issue with sending multicast traffic between VLANs on the same core switch
So for example on our switch we have VLANs 100 and 101
We can send multicast traffic from VLAN 100 to VLAN 101. However, a source from VLAN 101 cannot send multicast traffic to VLAN 100.
All the VLANs, source and receivers are on the same switch and we can ping between the sources and receivers.
