Configuring the routing table is the job of the route command. NOTE The path between two arbitrary computers on the Internet typically includes a dozen or more routers, but your computer needs to know only the address of the first of these, and of the destination system. The first router knows how to reach the next one, and so on until the final destination computer is reached. Understanding Routing Table Structure The routing table consists of a series of entries specifying what to do with packets sent to certain ranges of IP addresses.

3. This figure depicts an environment in which an organization has connected two subnetworks via routers. The regular computers in both offices can be configured quite simply—they need only point to their local routers as their gateways. Likewise, the router in Office 2 can point to the router in Office 1 as its sole gateway system, although the Office 2 router has two interfaces, as just discussed. The router in Office 1, however, requires a more complex configuration. 0/16 network. 3. Routers with more than two interfaces require at least two gateway definitions in order to function properly.

Com to register it. Thanks Chapter 2. TCP/IP Network Configuration Although the Linux kernel lies at the heart of any Linux system and controls all network access, the process of configuring a Linux computer to use a network involves more than the kernel. This chapter covers three popular methods of network connection: the Dynamic Host Configuration Protocol (DHCP), static IP addresses, and the Point-to-Point Protocol (PPP). DHCP and PPP are used to automatically assign an IP address and set other configuration information, but in different contexts.
