3.4 DHCP Relay Configuration Example
I. Network requirements
The DHCP clients on the network segment 10.110.0.0/16 are connected to a port of
VLAN 2. The IP address of the DHCP server is 202.38.1.2. DHCP packets between
the DHCP clients and the DHCP server are forwarded by the DHCP relay, through
which the DHCP clients can obtain IP addresses and related configuration information
from the DHCP server.
