Figure 5-9 Principle of DHCP Relay
Step 1 The DHCP client sends a request packet to the DHCP server.
Step 2 After receiving the packet, the DHCP relay device process the packet in a certain way, and
then sends it to the DHCP server on the specified network segment.
Step 3 The DHCP server sends acknowledgement packet to the DHCP client through the DHCP
relay device according to the information contained in the request packet. In this way, the
configuration of the DHCP client is dynamically configured.
5.6.2 Preparing for configurations
Scenario
When DHCP Client and DHCP Server are not in the same network segment, you can use
DHCP Relay to make DHCP Client and DHCP Server in different network segment bear relay
service, and relay DHCP protocol packet across network segment to destination DHCP server,
so that DHCP Client in different network segment can share the same DHCP Server.
Prerequisite
DHCP Relay is exclusive to DHCP Server, DHCP Client, or DHCP Snooping. Namely, you
cannot configure global DHCP Server, DHCP Client, or DHCP Snooping on the device to be
configured with DHCP Relay.
5.6.3 Default configurations of DHCP Relay
Default configurations of DHCP Relay are as below.
