Network requirements
As shown in
Figure 4
, hosts are connected to the switch, which is connected to the router through
interface GigabitEthernet 1/0/1 in VLAN 10. The IP and MAC addresses of the router are
192.168.1.1/24 and 00e0-fc01-0000 respectively.
To prevent malicious users from attacking the switch and enhance security for communications between
the router and switch, configure a static ARP entry for the router on the switch.
