Multicast Router with 2.1.0R ?

[Joao Carlos Mendes Luis]

Hello,

I' trying to implement a multicast router with FreeBSD 2.1.0. I got the
3.8 version of mrouted, compiled and all seemed ok. Multicast tunnels
seens to work well. But I have a question: I can only see one route
to the 224.0.0.0 network, but I have 2 network cards. I cannot add a
second route to the 224 network in the second card. Is this a limitation
in the kernel ? Should I make any change to the phyint parameters in
the mrouted.conf to make it work in both interfaces ?

TIA,

Jonny

you can run /usr/sbin/mrinfo to see the status of your interfaces or start
the mrouted in debug mode.

another test is to run tcpdump on all the interfaces looking for multicast
packets:

for i in ${INTERFACES}
do
tcpdump -i $i net 224.0.0.0
done

--mark.
