The RIP is an internal address that LVS uses in order to be able
to send packets from the linux director to the real server, 
else it wouldn't know where they should go.

As for public vs. private. It is usual to have the VIP on a public
address and the RIPs on private addresses. But this is by no means
required. You can use whatever addresses you like. Just remember
that the end-users need to be able to send packets to the VIP.
