Figure 56 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 2) are sent to the other DHCP server with IP address 172.16.10.100.
