To achieve data backup to the central backup site, an iSCSI connection between site A and
site B must be set up first, and then a logical connection needs to be established by adding a
route and a target. Before setting up the connections, a detailed networking plan must be
drawn.
Table 4-5 describes the IP address plan for site B.
