Network requirementsAs shown in Figure 2-1, the host’s interface and VLAN-interface 3 of Switch A are onthe same network segment (1.1.1.0/24). VLAN-interface 2 of Switch A andVLAN-interface 2 of Switch B are on another network segment (2.2.2.0/24). The defaultgateway of the host is VLAN-interface 3 (IP address 1.1.1.2/24) of Switch A. Configurea static route on Switch B to enable the reachability between host and Switch B.
