DHCP Servers
Both DHCP servers become
members in their respective
VLANs via IP subnet rules.
Routers
Router 1 provides connectivity
between the Test VLAN and
the Production VLAN. It does
not have Bootp functionality
enabled so it cannot connect
DHCP servers and clients from
different VLANs.
Router 2 connects the Produc-
tion VLAN and the Branch
VLAN. With Bootp relay
enabled, this router can pro-
vide connectivity between the
DHCP server in the Branch
VLAN and the DHCP clients in
the Production VLAN.
DHCP Clients
Clients 1 to 6 are assigned to
their respective VLANs through
DHCP port rules. Clients 3 and
4 are not in a VLAN with a
DHCP server so they must rely
on the server in the Branch
VLAN for initial addressing
information. Clients 7 and 8
share a port with other devic-
es, so they are assigned to the
Branch VLAN via DHCP MAC
address rules.
