pimd Multicast routing with Airtame

jadyn.dev

I have a setup where multiple TV's (with Airtame devices) are connected to a VLAN. Users should be able to connect to these devices via AirPlay and similar services. Therefore the devices have to discover each other via multicast.
The client devices are located in there own VLANs. It looks like this:

I've tried to configure the new PIMD package (V 0.0.2) it lists the Airtame devices as expected. But the multicast traffic is not forwarded to the other clients. The pimd.conf looks like this:

default-route-distance 101
default-route-metric 1024
igmp-querier-timeout 180
phyint em2 enable
phyint em3 enable
phyint em1 enable
rp-candidate em3
	group-prefix 239.255.255.250
	group-prefix 224.0.0.251
rp-candidate em2
	group-prefix 239.255.255.250
	group-prefix 224.0.0.251
rp-candidate em1
	group-prefix 239.255.255.250
	group-prefix 224.0.0.251
rp-address 10.0.3.1 239.255.255.250
rp-address 10.0.3.1 224.0.0.251
rp-address 10.0.2.1 239.255.255.250
rp-address 10.0.2.1 224.0.0.251
rp-address 10.0.1.1 239.255.255.250
rp-address 10.0.1.1 224.0.0.251

As stated in the release notes, it may be possible to create invalid configurations with the GUI.
