IP ROUTINGNETWORK WITHREMOTEBRIDGEDEVICES

Configure the CyberSWITCH

CONFIGURE THECYBERSWITCH

Using the detailed instructions found in the Simple Remote Bridging chapter, complete the configuration steps listed below.

Note: The software should have already been installed and the system prompt should be displayed before beginning the configuration.

Start the CFGEDIT program

Select physical resources

Select to add a resource

Select Switch type to be NI-1

Select to add a line

Select slot 1, port 1

Enter “Line1” as the line name

Add Data Links

Choose Auto TEI Negotiation

Enter SPID Value

Enter Directory Number for Data Link

Enter Maximum Number of Digits to Verify

Repeat “Add Data Links” for second Data Link

Repeat “Select to add a line” for each additional line

The following sections provide instructions for completing the remaining configuration steps.

CONFIGURING THECYBERSWITCH OPTIONS

To begin the configuration of the system options, press 2 at the Main Menu. The options menu will then be displayed.

ENABLE/DISABLEBRIDGING

Whether or not to use bridging depends on network requirements. The RLAN interface will work either way. For this example, we will assume that we only want to route IP traffic onto the corporate LAN. Therefore, we will disable bridging on the CyberSWITCH. IP routing is already enabled as fault, so no change is necessary.

For this example, the only other IP information we need to configure is two IP interfaces. (No static routes are needed.) The next section will provide the instructions needed to configure the necessary IP interfaces.

CONFIGURING THEIP INTERFACEINFORMATION

In our example, we need to configure two types of interfaces. The LAN interface represents the system connection to the LAN IP Network 128.1.0.0. The WAN RLAN interface represents the system connection to the remote IP network 198.12.10.0.

Press 2 at the IP main menu to begin the configuration of the IP interface information. Press 1 to add an IP interface. Select the LAN interface option from the list of possible interface types.

EXAMPLE NETWORKS

The interface name is a symbolic name given to the interface. For the LAN interface, use a name that describes the LAN, such as the name of the site or department. Type CorpOffice for this example.

You will then be asked for the IP address for the interface. In our example, the value you should enter is 128.1.1.1. You will then be asked for the IP subnet mask information. In our example, we are using a Class B address (without any subnetwork addressing) that requires 16 bits of the address to define the network number. Press <return> to accept the default of “16” significant bits. Press <return> to accept the default packet encapsulation type (Ethernet). Press <return> to accept the default of 1500 as the MTU size.

Press <return> to accept the default transmit broadcast address. For almost all devices, this address will allow the transmission of the broadcast to all devices on the local network. For some older devices, you may need to try some of the other selections to get the transmission to work correctly.

The rest of the LAN information requested pertains to the system’s RIP capability on the LAN (if RIP is enabled). For the rest of the required RIP LAN interface information, accept the default values. If RIP is disabled, no RIP prompts will be displayed.

The sequence of prompts will be similar to the following:
