Packet Forwarding and Routing on IPv4 Networks (System Administration Guide: IP Services) [2]
This section contains procedures and examples that show how to configure forwarding and routing for routers and hosts on IPv4 networks.. Packet forwarding is the basic method for sharing information across systems on a network
When you issue a command or send a message to a nonlocal interface, your system forwards those packets onto the local network. The interface with the destination IP address that is specified in the packet headers then retrieves the packets from the local network
By default, packet forwarding is automatically configured when you install the Solaris OS.. Routing is the process by which systems decide where to send a packet

NAT or Network Address Translation is the process of modifying the IP packet header information on packets going outside the corporate network. Corporate networks typically use private addresses on the inside LAN and need a public address to be able to communicate through the WAN.
The setup mode can be interrupted at any time using the Ctrl-C key combination.. Within a production network, what is the purpose of configuring a switch with a default gateway address?
CS425: Computer Networks: Lecture 10 [7]
The network layer is concerned with getting packets from the source all the way to the destination. The packets may require to make many hops at the intermediate routers while reaching the destination
In order to achieve its goals, the network layer must know about the topology of the communication network. It must also take care to choose routes to avoid overloading of some of the communication lines while leaving others idle
– Routing – The process of transferring packets received from the Data Link Layer of the source network to the Data. Link Layer of the correct destination network is called routing

Network layer [9]
In the previous chapter, we looked at the role of the OSI transport layer in communication. We will discuss the addressing used, the functions, and the different network layer protocols, introduce IPv4, understand how packets move in the network and finally give an overview in how we address the network using IPv4
The network layer defines communication over the network through four basic processes which are addressing, routing, encapsulation and decapsulation. You may have sent a letter through the post office, while doing this, you are required to write the address of the recipient on the envelope and most likely your address for reply purposes.
However, unlike the postal addresses, addressing in the network layer is logical. This means that addresses are not fixed to the devices and they may change.
Fundamentals of IP for the CCNA INTRO Exam #640-821 [10]
A protocol that defines routing and addressing is considered to be a network layer, or Layer 3, protocol. OSI does define a unique Layer 3 protocol called Connectionless Network Services (CLNS), but, as usual with OSI protocols, you rarely see it in networks today
The network layer protocols have many similarities, regardless of what Layer 3 protocol is used. In this section, network layer (Layer 3) addressing is covered in enough depth to describe IP, IPX, and AppleTalk addresses
Routing focuses on the end-to-end logic of forwarding data. Figure 5-1 shows a simple example of how routing works
Guidelines for Assigning Network Layer Addresses [11]
Network layer addresses should be planned, managed, and documented. Although an end system can learn its address dynamically, no mechanisms exist for assigning network or subnet numbers dynamically
These networks are hard to troubleshoot and do not scale.. The following list provides some simple rules for network layer addressing that will help you architect scalability and manageability into a network design
• Design a structured model for addressing before assigning any addresses.. If you do not plan for growth, you might later have to renumber many devices, which is laborintensive.

Use LEFT and RIGHT arrow keys to navigate between flashcards;. In an IPv4 enviorment, what information is use by the router to forward data packets from one interface of a router to another?
In a connectionless system, which of the following is correct?. The destination is not contacted before a packet is sent.
Using the network in the exhibit, what would be the default gateway address for host A in the 192.133.219.0 network?. If the default gateway is configured incorrectly on the host, what is the impact on the communications?
Network Fundamentals – Layer 3 Technologies [13]
Although each network interface has a unique MAC address, this does not specify the location of a specific device or to what network it is attached, meaning a router cannot determine the best path to that device. In order to solve this problem, Layer 3 addressing is used.
Network layer addresses have a hierarchical structure comprised of two parts: the network address and the host address. Logical addresses can be assigned manually by the administrator or dynamically via a dedicated protocol, such as Dynamic Host Configuration Protocol (DHCP)
This addressing structure is illustrated in Figure 1.23 below, both for IPv4 and for IPv6. The IPv4 and IPv6 address structures will be covered in detail in Chapter 6.
Internetworking Layer (IP) [14]
Now that we can move data across a single link, it’s time to figure out how to move it across the country or around the world. To send data from your computer to any of a billion destinations, the data needs to move across multiple hops and across multiple networks
A packet also needs to take multiple forms of transportation to reach its destination. For a packet taking its “trip” to another country, the “walk”, “bus”, “train”, and “plane” can be thought of as different link layers like WiFi, Ethernet, fiber optic, and satellite.
There might be hundreds of other people on the same bus, train, or plane, but your trip is different from that of every other traveller because of the decisions that you make at the end of each of your “hops”. For instance, when you arrive at a train station, you might get off one train, then walk through the station and select a particular outbound train to continue your journey
