DHCP Relay is introduced to solve this problem. It can provide relay service between DHCP
clients and the DHCP server that are in different segments. It relays packets across segments
to the DHCP server or clients.
Figure 6-14 shows typical application of DHCP Relay.
Figure 6-14
Typical application of DHCP Relay
When a DHCP client sends a request packet to the DHCP server through a DHCP relay, the
DHCP relay processes the request packet and sends it to the DHCP server in the specified
segment. The DHCP server sends required information to the DHCP client through the DHCP
relay according to the request packet, thus implementing dynamic configuration of the DHCP
client.
6.6.2 Preparing for configurations
Scenario
When DHCP Client and DHCP Server are not in the same segment, you can use DHCP Relay
function to make DHCP Client and DHCP Server in different segments carry relay service,
and relay DHCP protocol packets across segment to destination DHCP server, so that DHCP
Client in different segments can share the same DHCP server.
