I need to run mrouted on a 3.1-R system to make multicast sessions
available in at less one of our local subnets. I didn't get any success
til now. Tools like sdr, vic and others only show traffic on the host
running mrouted itself. No system on the subnet gets multicast packages
unless the corresponding tool is started on routing host itself.
----------
Here's the output of ifconfig (IP addresses changed):
de0: flags=3D8a43<UP,BROADCAST,RUNNING,ALLMULTI,SIMPLEX,MULTICAST> mtu 1500
inet 112.18.5.63 netmask 0xffffff00 broadcast 112.18.5.255
ether 00:80:c8:4a:d3:d1=20
media: autoselect (100baseTX <full-duplex>) status: active
supported media: autoselect 100baseTX <full-duplex> 100baseTX
10baseT/UTP <full-duplex> 10baseT/UTP
----------
/etc/mrouted.conf looks like:
# Multicast Routing
tunnel 112.18.5.63 138.11.165.21 metric 1 threshold 16 rate_limit 2000
As mentioned above, the tunnel is ok, but there's no propagation to the
subnet unless someone invokes an mbone tool on 112.18.5.63 itself.
----------
The kernel config file contains - of course - :
options MROUTING #Multicast Routing

`mrouted -d interface' prints:

Would be nice if somebody has an idea!
