I still have misunderstood here. Pimd installs multicast routes and this

So, the system knows interface where multicast received.
When Join received via interface 2 (vlan299) who must resend multicast from
input interface 3 (vlan750)
to output interface 2 (vlan299)? I guess it kernel-specific task and kernel
must resend multicast
without any other helpers. Is it wrong?
I'm not familiar with multicast routing in FreeBSD.
Multicast routing has its rules in general, though.
For example, Cisco routers never process incoming multicast UDP flows if
unicast route
to source IP address of UDP packets points to interface that differs from real
incoming interface.
This is "reverse path filtering" embedded in multicast routing unconditionally.
Yes, but FreeBSD can ping source and client in my tests (see my new
later at this thread with network scheme)
