Application Example: DHCP Policies
Page 20-28
DHCP Servers and Clients
DHCP
clients must be able to communicate with a
DHCP
server at initialization. The most reli-
able way to ensure this communication is for the server and its associated clients to share the
same
VLAN
or mobile group. However, if the network configuration does not lend itself to
this solution (as the Production
VLAN
does not in this application example), then the server
and clients can communicate through a router with Bootp relay enabled.
The
DHCP
servers and clients in this example are either in the same
VLAN
or are connected
through a router with Bootp relay. All clients in the Test
VLAN
receive IP addresses from the
server in their
VLAN
(Server 1). Likewise, all clients in the Branch
VLAN
receive IP addresses
from their local server (Server 2). The
DHCP
clients in the Production
VLAN
do not have a
local
DHCP
server, so they must rely on the Bootp relay functionality in external Router 2 to
obtain their IP addresses from the
DHCP
server in the Branch
VLAN
.
Both
DHCP
servers gain membership to their
VLAN
s through IP network address policies.
The following table summarizes the
VLAN
architecture and policies for all devices in this
network configuration. The diagram on the following page illustrates this network configura-
tion.
