Ignoring arp on specific interfaces.. How to?

[Naoki <naoki valuecommerce com>]

Hi all,

    I have a box with a dummy0 interface and I want eth0 to ignore arps
for that interface.

All the docs I can find (http://www.austintek.com/LVS/LVS-
HOWTO/HOWTO/LVS-HOWTO.arp_problem.html) seem to say set arp_ignore to
'1' and arp_annonce to '2'. This however does nothing in my tests.


# ls -l /proc/sys/net/ipv4/conf/eth0/*arp*
-rw-r--r--  1 root root 0 Jan 19
14:52 /proc/sys/net/ipv4/conf/eth0/arp_announce
-rw-r--r--  1 root root 0 Jan 19
14:52 /proc/sys/net/ipv4/conf/eth0/arp_filter
-rw-r--r--  1 root root 0 Jan 19
14:52 /proc/sys/net/ipv4/conf/eth0/arp_ignore
-rw-r--r--  1 root root 0 Jan 19
14:52 /proc/sys/net/ipv4/conf/eth0/proxy_arp

arp_filter might do the trick but before I dig into source code has
anybody already done this and can tell me what I need for a working
system?

eth0   - 192.168.168.10
dummy0 - <some public IP>

I want eth0 to behave as normal and for 'arp who has <public IP>'
requests to be ignored by dummy0.
