## IP-routing environment

Figure E-1 illustrates the main office and three remote offices of Smith Company. All sites support IP routing. Twelve dial-in analog circuits are available for employees to dial into the corporate office while traveling. The remote sites and dial-in users access the Internet by way of the corporate office.

The corporate site belongs to the 10.10.10.0 network. The remote sites share subnetted segments of the 20.20.20.0 network. The corporate site maintains a 128k link to the Internet, and also reserves twelve connections available for employees to dial into while traveling. The MAX dynamically assigns up to ten dial-in users with IP addresses from a pool that begins with the address 10.10.10.40.

## IP-routing and AppleTalk-routing environment

As another example, Smith Company adds AppleTalk devices to the network and sets up an AppleTalk-routed environment, illustrated in Figure E-2. All sites support IP routing and AppleTalk routing. Twelve dial-in analog circuits are available for employees to dial into the corporate office while traveling. The remote sites and dial-in users access the Internet by way of the corporate office.

For the company's IP-routed environment, the corporate site belongs to the 10.10.10.0 network. The remote sites share subnetted segments of the 20.20.20.0 network. The corporate site maintains a 128 kbps link to the Internet, and also reserves twelve connections available for employees to dial into while traveling. The MAX dynamically assigns up to ten dial-in users with IP addresses from a pool that begins with the address 207.107.84.40.

Four zones are created for the company's AppleTalk-routed environment: Corporate, SiteA, SiteB, and SiteC. Devices that share the Ethernet segment with the MAX unit belongs to network 100-150. Devices that share the Ethernet segment with the SiteA Pipeline belong to network 200-210. Devices that share the Ethernet segment with the SiteB Pipeline belong to network 300-300. Devices that share the Ethernet segment with the SiteC Pipeline belong to network 700-700.
