Multicast Routing

I use LocalSend but I have like 3 or 4 VLANs that I would want them to work across. Now I read a lot about very different software that might be able to help me here like:

  • frr-pimd
  • smcroute
  • igmpproxy
  • mcproxy

Could someone please shed some light into this topic? The Multicast article from OpenWrt mainly focuses on forwarding WAN IPTV to LAN members.
