Network requirements
As shown in Figure 39 , hosts are connected to the SecBlade, which is connected to the router through
interface GigabitEthernet 0/2 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 SecBlade and enhance security for communications
between the router and SecBlade, configure a static ARP entry for the router on the SecBlade.
