Routing

Routing Overview

This chapter provides instructions for the module’s routing configuration. At

this point, you have chosen to operate the module in routing mode because

you want to take advantage of these features:

■ Firewall

• Port Triggers

• Application-level gateway (ALG)

• Network address translation (NAT)

■ Intrusion prevention (IPS)

■ Virtual private network (VPN)

■ High availability (HA) clusters

■ Web authentication

In order to implement these features, the module must route packets to their

destination, so it functions as another router that is connected to the host

switch. The TMS zl Module’s data port is tagged member of all VLANs that are

configured on the module, called TMS VLANs. Because the TMS zl Module’s

data port is tagged for all of the TMS VLANs, when the switch receives a packet

that is destined for the TMS zl Module’s MAC address, it bridges the packet to

the TMS zl Module with the appropriate VLAN tagging.

This chapter will describe the routing methods and protocols supported by

the module as well as provide step-by-step instructions for configuring routing

on the module. After you have finished configuring routing on the module, the

module should integrate seamlessly with your network to route packets

without negatively impacting throughput.

The TMS zl Module supports the following routing capabilities:

■ Static routing

■ Routing Information Protocol (RIP)

■ Open Shortest Path First (OSPF)

■ Multicast routing

The TMS zl Module can support up to 10,000 total routes (including redistrib-

uted routes).

Note You cannot enable routing on a VLAN for which DHCP relay is enabled.
