Why are only IPv6 entries shown, what happened to the IPv4 entries? IPv6 Entries are the only ones being populated with the avahi-browse when run from a different vlan.
Setup IGMP, PIM on L3 switch with a vSphere ubuntu or VyOS vm todo mDNS reflection which is providing discoverability between vlans. However chromecast and tv have not been successful so far but figured if I could find out why only IPv6 is working maybe that might shed more light on the bigger issues.
From one vlan to another(vm on):
all entries are wirelessly connected to an AP in all snippets

When connected to the same wifi network and vlan mDNS queries are sent using both address and devices respond with IPv4 and IPv6, except the chromecast(ipv4). In the above responses are sent with both ip formats but the queries only seem to be sent with IPv6, chromecast no where to be found.
