Hi Thanks for Suggestion, You are right !! But then I come up with other easy solution.. Without applying patch

When I ran "route" command, I found NIC1( eth0 ) was in my default route:10.10.10.0 * 255.255.255.0 U 0 0 0 eth2 10.168.1.0 * 255.255.255.0 U 0 0 0 eth1 169.254.0.0 * 255.255.0.0 U 0 0 0 eth2 192.168.0.0 * 255.255.0.0 U 0 0 0 eth0 default headnode.direct 0.0.0.0 UG 0 0 0 eth0
I deleted that entry: route del -net default
Then, I added my NIC2( eth2 ) as default NIC: route add default gw 10.10.10.82 eth2 :
Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.10.10.0 0.0.0.0 255.255.255.0 U 0 0 0 eth2 10.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth2 192.168.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 0.0.0.0 10.10.10.82 0.0.0.0 UG 0 0 0 eth2
Now Iperf ran on NIC2 path

|    Hi users,
| 
|    I have multiple NIC card on my PC like:
|    Server:
|    SERVER_NIC1: 192.168.54.82
|    SERVER_NIC2: 10.10.10.82
| 
|    Client:
|    CLIENT_NIC1: 192.168.54.83
|    CLIENT_NIC2: 10.10.10.83
| 
|    Now suppose I find out below commands to test Iperf Multicast:
|    Server: iperf -u -B 230.17.17.1 -s -t 60 -i 5 -l 1K -P 1 -p 5001
|    Client: iperf -u -B 192.168.54.83 -c 230.17.17.1 -t 60 -i 10 -l 2k -P 1 -p
|    5001
| 
|    And its worked but when ran commands for NIC2 like:
|    Server: iperf -u -B 230.17.17.1 -s -t 60 -i 5 -l 1K -P 1 -p 5001
|    Client: iperf -u -B 10.10.10.83 -c 230.17.17.1 -t 60 -i 10 -l 2k -P 1 -p
|    5001
| 
|    Server didn't response and seems that it was not hearing on 10.10.10.XX
|    IP.
| 
|    How can I Run Multicast test on NIC2 / Else than Default NIC ? Do any one
|    have any Command OR Solution ?
|    Thanks,
|    Dharmesh

As far as I know, iperf does not support setting the multicast interface. Doing this
is however required when running UDP multicast on a multihomed box. The fix should
be easy, you can check for IP_MULTICAST_IF in the manpage of ip(7).
