@tc10284 said in Multicast Sessions not starting:
The FOG server is on a separate VLAN - 10.80.50.0/24 and the workstations are on 10.80.128.0/24.
Two Cisco switches. There should be not known filtering or blocking of multicast traffic, unless I need to change something on the switches. I can provide the switch config if needed.
Be aware that unless you have a multicast router in place this will not work. standard IP routers will not forward multicast packets between subnets. you need an mrouter for that. Multicast imaging is really a different kind of bird. You should have igmp snooping enabled on your switches and if your switches support it on the correct vlans too, to avoid flooding your network with multicast packets.
Also only “normal” fog servers can send multicast images. Storage nodes can’t do this in the current release of FOG.
