Overview
Routing
Routing
When it operates in routing mode, the TMS zl Module must be able to route
the traffic that it is filtering and analyzing for threats. The module’s VPN
capabilities also require the module to know the correct routes.
The module supports these routing capabilities:
■ Static routing
■ Routing Information Protocol (RIP)
■ Open Shortest Path First (OSPF)
The TMS zl Module supports up to 10,000 total route entries, including static
and dynamic routes.
Static Routing
The TMS zl Module automatically routes traffic between connected VLANs.
You can add three types of static routes:
■ One default route (through the default gateway)
■ Routes to particular hosts
■ Routes to networks
RIP
The TMS zl Module supports RIP versions 1 and 2. You can choose the version
for messages that are sent and received on each VLAN. However, the module
does not support RIP compatibility mode. The module does support passive
interfaces, which are VLANs that receive, but do not advertise, routing
updates.
By default, the TMS zl Module does not redistribute routes to its own con-
nected VLANs. In other words, the module only advertises routes to the VLANs
on which you enable RIP. However, you can configure the module to redistrib-
ute connected routes as well as static routes and routes discovered through
OSPF. You can configure the metric for redistributed routes, but all types of
redistributed routes have the same metric.
