Pavlin,
My mistake, when i say that the next-hop 193.191.130.193 should be
the juniper router i talk on the multicast point of view. So you right
my default unicast route is through the eth0 as i want that unicast and 
multicast traffic travel through different interface. As i have say in 
previous post, the box acting as firewall. I want to disociate traffic on
different interface because the firewall is on the same subnet as others
BELNET server. And i doesn't want that multicast traffic pollute statistic of 
unicast traffic of the servers (we are not able to use IGMP snooping on the 
switch)

So there is a possibility to have on linux, different table for unicast and 
multicast routing. What i mean here is there is a way to let multicast use
other routing table to make RPF ? Does XORP permit this ?

Also , i doen't know if this is the best way or if this is needed or if it is 
completely silly do make this.

echo 0 > /proc/sys/net/ipv4/conf/all/rp_filter

Thanks a lot for your help.

Philippe.
