Hi List,
I have the following setup:
One host with two interfaces (eth0, eth1):

eth0 Link encap:Ethernet HWaddr 00:E0:4C:71:05:92
inet addr:10.1.12.87 Bcast:10.1.12.255 Mask:255.255.255.0
inet6 addr: fe80::2e0:4cff:fe71:592/10 Scope:Link
UP BROADCAST NOTRAILERS RUNNING MTU:1500 Metric:1
RX packets:4512 errors:0 dropped:0 overruns:0 frame:0
TX packets:4034 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
RX bytes:345507 (337.4 Kb) TX bytes:407841 (398.2 Kb)
Interrupt:11 Base address:0x5000

eth1 Link encap:Ethernet HWaddr 00:E0:4C:71:05:91
inet addr:10.1.12.151 Bcast:10.1.12.255 Mask:255.255.255.0
inet6 addr: fe80::2e0:4cff:fe71:591/10 Scope:Link
UP BROADCAST NOTRAILERS RUNNING MTU:1500 Metric:1
RX packets:2709 errors:0 dropped:0 overruns:0 frame:0
TX packets:16 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
RX bytes:239132 (233.5 Kb) TX bytes:2646 (2.5 Kb)
Interrupt:10 Base address:0x7000

when I do
ping -I eth0 10.1.12.151
I don't get a reply but ARP requests like this:

19:23:59.219402 arp who-has 10.1.12.151 tell 10.1.12.87
19:24:00.219402 arp who-has 10.1.12.151 tell 10.1.12.87
19:24:01.219402 arp who-has 10.1.12.151 tell 10.1.12.87
19:24:02.219402 arp who-has 10.1.12.151 tell 10.1.12.87

So the host tries to resolve its own MAC address and does
not answer itself. Manually setting the ARP entry fails
as well.

Question: Should this work at all? If yes, is there a fix?
