DHCP Server
The external router inserts the subnet address of the first hop segment into the DHCP request frames from
the DHCP clients. This subnet address allows the DHCP server to locate the segment on which the
requesting client resides. In this example, all clients attached to the OmniSwitch are DHCP-ready and will
have the same subnet address (130.0.0.0) inserted into each of the requests by the router's DHCP Relay
function. The DHCP server will assign a different IP address to each of the clients. The switch does not
need an IP address assigned and all DHCP clients will be members of either a default VLAN or an IP
protocol VLAN.
