Configuration example
Network requirements
As shown in Figure 55 , the interface of Host A and VLAN-interface 3 of Switch A are located on network
segment 1.1.1.0/24. VLAN-interface 2 of Switch A and VLAN-interface 3 of Switch B are located on
network segment 1.1.2.0/24. VLAN-interface 2 of Switch B, Host B, and Host C are located on network
segment 1.1.3.0/24. The default gateway of Host A is VLAN-interface 3 (IP address 1.1.1.1/24) of Switch
A. The default gateway of Host B and Host C is VLAN-interface 2 (IP address 1.1.3.1/24) of Switch B.
Configure static routes on Switch A and Switch B for reachability between Host A and Host B, and Host
A and Host C, respectively.
Enable forwarding of directed broadcasts on Switch A and Switch B so that Host C and Host B can
receive directed broadcasts from Host A.
