I have 2 Core x M4300-24X24F ProSAFE 24-port 10GBASE-T and 24-port 10G SFP+ stacked together on ports 45-48
I then have;
1 x Edge1 M4300-52G ProSAFE 48-port 1G and 2-port 10GBASE-T and 2-port 10G SFP+ connected to ports 1:1 & 2:1 LAG
1 x Edge2 M4300-52G ProSAFE 48-port 1G and 2-port 10GBASE-T and 2-port 10G SFP+ connected to ports 1:2 & 2:2 LAG
These switches are being used for KVM over IP using Adder KVMs
Multicasting is enabled on all switches which is required for the KVM to be used in several receivers at once - one to many video/audio USB,
KVM has been assigned to VLAN 172

Edge 2 setup the same as Edge 1 with a Snooping Querier Address:1169.254.100.102
Devices on Edge 1 work perfectly fine with IGMP multicast allowing multiple streams of KVM audio and video to several receivers.
However Any Device on Edge 2 cannot correctly receive multicast information from edge 1 and vice versa, they seem to receive a multicast IP in the adder management, but will not pass video streams/traffic.
What am I missing or whats configured incorrectly?
