ProCurve Wireless Edge Services zl Module
Figure 1-9. Designing VLANs for a Wireless Network That Includes Multiple
Modules
Now that you have considered the services that your Wireless Edge Services zl
Module should provide, you can start to look at individual services in more detail.
The following sections describe the capabilities of the module, including, in addition
to the Layer 3 services introduced above, the module’s many capabilities in securing
and managing the wireless network.
IP Routing
The module can implement basic routing between its VLANs. It can have up to eight
directly connected routes (one on each VLAN interface), and you can manually add
static routes. The module also has one active default route.
IP routing is disabled by default. Even if wireless stations use a different router, you
might want to enable IP routing because several module capabilities require routing
to be active. These functions are:
■ DHCP relay
■ the internal firewall
■ IP ACLs applied to logical (VLAN) interfaces
■ NAT
