Network requirements
As shown in Figure 34, Host A and Host D have the same prefix and mask (the IP addresses of Host A
and Host D are 192.168.10.100/16 and 192.168.20.200/16 respectively, and the two IP addresses
belong to the same network 192.168.0.0/16), but they are located on different subnets separated
through LB module.
As no default gateway is configured for Host A and Host D, you need to configure proxy ARP on LB
module to enable the communication between Host A and Host D.
