The network shown in the previous example can be created with the following load-
balance commands:
Session and Netmask Persistence
In the following example, traffic to a company web site (www.ctron.com) is distributed
between two separate servers. In addition, client traffic will have two separate ranges of
source IP addresses. The same load balancing server will handle requests from clients of
the same source IP subnet address.
The network shown above can be created with the following load-balance commands:
load-balance create vip-range-name mywwwrange 207.135.89.16-207.135.89.50
virtual-port 80 protocol tcp
load-balance add host-to-vip-range 10.1.1.16-10.1.1.50 vip-range-name mywwwrange
port 80
load-balance add host-to-vip-range 10.1.2.16-10.1.2.50 vip-range-name mywwwrange
port 80
