Hello,
Hello,
first thing: I do not have any experience with multicast traffic.
But what you have build seems very strange to me. First you use vlan to
separate the networks an then you put them alltogether with a bridge.
I do not see the use of the vlans.
Its needed because all those streams are already on one vlan, but its
really needed to "extract" address based. Its the best way to put
different streams on different vlans (using cisco switch is not a very
good idea for this task, because some limitations, but its out of
current topic).
Wouldn't it be better to not use the bridge and use (multicast-)routing
and pf to solve your problem?
Multicast routing with "dvrmpd" is tested with pf, does not work. the
same thing happens, if streamX is allowed to pass out on vlanX and
streamY is allowed to pass out on vlanY, result is pretty similar:
vlanX outputs both streams (streamX, streamY) and the same thing with
vlanY. pf is not 100% percent multicast compat.?
As I said, I have no experience with multicast traffic, but that is how
I would start digging.

I have a problem with pf+bridge+vlan (multicast traffic) and I googled
a lot, read the manuals and so on - no help. Finally I posted on wrong
place :( sorry.
Hopefully this time I'm writing to right place.
Following setup is made for multicast traffic separation from one lan
to multiple vlans.
Setup:
Two physical interfaces
bnx0
bnx1
interfaces bnx0 and bnx1 has vlans:
bnx0
vlan1100
bnx1
vlan1101
vlan1102
vlan1103
vlan1104
vlan1105
vlan1106
vlan1107
vlan1108
Bridge setup: bridge0 has all vlans as bridge members (vlan1100,
vlan1101 ... vlan1108)
PF config:
block out on bnx1 all
block out on vlan1100 all
block out on vlan1101 all
block out on vlan1102 all
block out on vlan1103 all
block out on vlan1104 all
block out on vlan1105 all
block out on vlan1106 all
block out on vlan1107 all
block out on vlan1108 all
pass out quick on vlan1101 proto udp from any to 239.16.1.1
pass out quick on vlan1102 proto udp from any to 239.16.1.2
pass out quick on vlan1103 proto udp from any to 239.16.1.3
Wishful thinking, what the result should be:
All multicast streams are available on vlan1100 and recieved via
"bnx0/vlan1100". Bridge should stream the multicast packets to what
ever vlan - its the place where pf should help. Stream: 239.16.1.1
should be available only on vlan1101, and 239.16.1.2 avialable on
vlan1102 and so on.
.
Real Result:
Stream 239.16.1.1 is available on all three vlans: 11101,1102,1103 -
same thing happens with other two streams (239.16.1.2, 239.16.1.3)
It's really weird what's going on or did I understood something wrong
and configuration is not correct?
Thank you.
