[lvs-users] a question about interface vip lo:0 in realserver in lvs dr mode

[寇善军 <fierceman@xxxxxxx>]

I have a question about interface vip lo:0 in realserver in lvs dr mode


most people used the command below to handle route to the interface VIP


 /sbin/route add -host $VIP dev lo:0 


I wonder what the command is used  for ?  if i did't configure it, what is the 
influence for the packets back to client from realserver ?
