Greetings all, ( Hi Monty and Jim )
 
I need to specify communication from a multicast IP to communicate on a specific Network Card.  My routing table appears as follows:
 
Destination                        Gateway                Genmask                Flags               MSS Window                irtt                I Face
 
216.198.99.0                      0.0.0.0                255.255.255.192        U                        0 0                             0                 eth1
10.0.0.0                             0.0.0.0                255.255.255.0            U                        0 0                             0                 eth0
169.254.0.0                        0.0.0.0                255.255.0.0                U                        0 0                             0                 eth1
0.0.0.0                              216.198.99.254     0.0.0.0                        UG                     0 0                             0                 eth1
 
I have 2 network cards.  One with the adress of 216.198.99.247  and a second NIC with an adress of 10.0.0.2.  The NIC with the 10. address is what I want to use for a failover communication with a second server.  The failover communication software uses a  multicast address of 229.255.0.1.  The default gateway is attached to the 216. network.  And ping tests result in the following:  Pinging from 10. NIC I can only receive replies from the other 10. address.  From the 216. NIC I receive replies from everything but I cannot establish the failover on this NIC.
 
What I want to do is tell my computer ( Red Hat Enterprise Linux V.3 ) to force communication from 229.255.0.1 across the 10.0.0.2 network card.  If I can accomplish this I believe my failover will work.
 
Thank you very much in advance for your assistance.
 
Note: I am not a Linux professional so please be very clear about suggestions.
 
Thanks Again,
