Hi
In LVS with Direct Routing(DR mode),you must configure the VIP on
loadbalancer and realservers with 32 bits netmask.
You may refer to my picture of LVS/DR structure on
http://blog.chinaunix.net/u2/74751/showart_1834194.html
I think you can figure out what should your configuration would be in your
case.
On real servers put the following lines in your /etc/sysctl.conf
net.ipv4.conf.lo.arp_ignore = 1
net.ipv4.conf.lo.arp_announce = 2
net.ipv4.conf.all.arp_ignore = 1
net.ipv4.conf.all.arp_announce = 2
To resole arp issues with LVS/DR.
Yours
