Dhcp Servers And Clients - Alcatel Omni Switch/Router User Manual

Application Example: DHCP Policies

DHCP Servers and Clients

clients must be able to communicate with a
DHCP
able way to ensure this communication is for the server and its associated clients to share the
same or mobile group. However, if the network configuration does not lend itself to
VLAN
this solution (as the Production
and clients can communicate through a router with Bootp relay enabled.
The servers and clients in this example are either in the same
DHCP
through a router with Bootp relay. All clients in the Test
server in their

local server, so they must rely on the Bootp relay functionality in external Router 2 to

Both servers gain membership to their

The following table summarizes the
network configuration. The diagram on the following page illustrates this network configura-
tion.
