Hello,
I seem to be having somewhat of a similiar problem with this as
well. I set a real IP on the loopback interface like so:
/sbin/ip addr add xxx.xxx.xxx.xxx/32 dev lo brd + scope host
then set the following
echo '2' > /proc/sys/net/ipv4/conf/lo/arp_announce
echo '1' > /proc/sys/net/ipv4/conf/lo/arp_ignore
However I still get ARPs for this IP. Is there something I am missing
here? I am trying to accomplish this on a Debian distro on a sparc64
with 2.6.4 kernel.
Btw, I was previously trying this with lo:0 as well :). Thanks for the
heads
up that this is deprecated.

Hi,
I have assigned the virtual IP to the realservers' lo:0 interface,
aliases (eg lo:0) have been deprecated since 2.4. There has been compatibility
maintained in 2.4, but I would not be surprised if it has been dropped in
2.6. I would expect that you should use
# ip addr add 82.115.225.254 brd 82.115.225.254 dev lo
route add -host 82.115.225.254 dev lo:0
But I get:
SIOCADDRT: Invalid argument
route/iptables etc doesn't know anything about lo:0
