IP ROUTING NETWORK

Configure the CyberSWITCH

CONFIGURING THE IP INTERFACE INFORMATION

In our example, we need to configure three types of interfaces (refer to the Network Topology Worksheet). The LAN type network interface represents the system connection to the IP Network

128.1.0.0on the LAN. The WAN (Direct Host) interface is a logical extension of the LAN IP network. Direct Host remote IP devices share the same IP address space as the IP network 128.1.0.0 on the LAN. The WAN network interface is a logical interface to an IP network connected to the CyberSWITCH over the ISDN. The reason we are using both a WAN and a WAN (Direct Host) Interface is to allow the two devices, Rick Bear and Ralph Moose, to call into somewhere else if need be.

We will begin by adding the LAN interface. Press 2 at the IP configuration menu to begin the LAN interface configuration. Press 1 to add an IP interface. Press 1 to select LAN as the type of interface that you wish to configure.

The interface name is a symbolic name given to the interface. For the LAN interface, you should use a name that describes the LAN. It could be the name of the site or department. Type SanFran 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. Therefore, 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 let the broadcast be transmitted 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 RIP feature. (This information will not be asked for if you have disabled RIP.) RIP is a protocol used to exchange routing information among IP devices. Using RIP can automate the maintenance of routing tables on IP devices and relieve you of having to keep the routing tables up to date manually. Static routes need to be configured manually if we need to access a WAN network that is not directly connected to the system, or if we need to access a LAN network through a router that does not support RIP.

RIP determines the shortest path between two points in a network in terms of the number of “hops” between these points.

For the rest of the required RIP LAN interface information, accept the default values.
