Figure 279 Example: Global DHCP Relay
This example shows how to configure the OLT for this configuration. DHCP relay agent information option
82 is also enabled.
In this example, there are two VLANs (VIDs 1 and 2) in a campus network. Two DHCP servers are installed
to serve each VLAN. The OLT forwards DHCP requests from the dormitory rooms (VLAN 1) to the DHCP
server with IP address 192.168.1.100. DHCP requests from the academic buildings (VLAN 3) are sent to
the other DHCP server with IP address 172.16.10.100.
