which the server will respond.

ODE
In translational mode, requests coming in to the VIP are translated to the IP address of
the server to be balanced. This mode does not require the configuration of a loopback
address, each server only needs to use its own IP address. As with any server load
balancing application, the content must be duplicated on all physical servers.
To configure translational mode, use the following command:
create slb vip <vipname> pool <poolname> mode translation <ipaddress>
{- <upper_ipaddress>}:{<L4Port>}
Figure 17-3 shows translational mode.
