DHCP relay agent configuration example
Network requirements
As shown in Figure 116 , DHCP clients reside on network 10.10.1.0/24. The IP address of the DHCP server
is 10.1.1.1/24. Because the DHCP clients reside on a different network with the DHCP server, a DHCP
relay agent is deployed to forward messages between DHCP clients and the DHCP server.
GigabitEthernet 0/1 of the DHCP relay agent (SecPath) connects to the subnet where DHCP clients
reside. The IP address of GigabitEthernet 0/1 is 10.10.1.1/24, and the IP address of GigabitEthernet 0/2
is 10.1.1.2/24.
