Configuration Example
Network requirements
As shown in Figure 11-1 , the host’s interface and VLAN-interface 3 of AC are on the same network
segment (1.1.1.0/24). VLAN-interface 2 of AC and VLAN-interface 2 of Switch are on another network
segment (2.2.2.0/24). The default gateway of the host is VLAN-interface 3 (IP address 1.1.1.2/24) of AC.
Configure a static route on Switch to enable the reachability between Host and Switch.
