CONFIGURING BASIC IP ROUTING

OVERVIEW

This chapter provides information for configuring basic IP routing features. Basic IP routing configuration includes:

•enabling/disabling the Internet Protocol (IP)

When you enable this option, the system operates as an IP Router. If you also enable bridging, it will route IP packets and bridge all other packet types.

•configuring the IP operating mode

The operating mode may be either host or router. The router operating mode is the default. The IP host mode allows you to use IP applications, such as Telnet and SNMP, without enabling IP routing.

•configuring network interfaces

Network Interfaces define the IP networks to which the CyberSWITCH provides access. If IP RIP is enabled, this also includes IP RIP interface information.

•configuring static routes (this includes default routes)

Other routers on the network that support IP RIP will not need static routes; IP RIP will maintain those routes. However, static routes must be configured to identify remote networks connected across the WAN, and for routers that do not support IP RIP.

•enabling/disabling IP RIP

IP RIP automates the maintenance of routing tables on IP devices.

A separate chapter, Configuring Advanced IP Routing, provides information for configuring advanced IP routing features. Advanced IP routing features include:

•configuring static ARP table entries

•enabling/disabling the isolated mode

•enabling/disabling static route lookup via RADIUS

•configuring the IP address pool

•configuring IP filters

•configuring DHCP

•configuring DNS and NetBIOS addresses

•configuring Security Associations for encryption

INTERNET PROTOCOL (IP) OPTION

ENABLING IP

USING CFGEDIT

1.Internet Protocol (IP) routing is disabled as a default. To begin the IP routing configuration, you must first enable IP routing. Select IP Routing from the Options menu.

2.Follow the onscreen instructions for enabling IP routing. Once IP has been enabled, the full IP Configuration menu will be displayed as shown below:
