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)
It does not matter if source is reachable with unicasts (ping). "Reverse"
unicast routes should match incoming interface for multicast UDP.
My network scheme is simplest:
---------- -------------------- -----------
| source |-vlan750-| FreeBSD PIM router |-vlan299-| client |
|200.5/29| |200.6/29 199.102/30| |199.101/30|
---------- -------------------- -----------
All multicasts comes from 200.5 with 200.5 as source IP. So I hope RPF
check passes for FreeBSD.
