Definition of ROUTING in Network Encyclopedia.. What is Routing (in computer networking)? ROUTING is the process of selecting a path through an internetwork over which to transmit packets to a destination host or hosts and then having devices called routers forward the packets to those hosts.

When the router wants to send a packet to the 192.168.1.0 network, it will look at the routing table. There is a route to that network via 192.168.2.3. Then the router checks to see whether it has an interface that to the 192.168.2.3 network. In this scenario, that would be the network highlighted in blue. The exit interface is serial 0/0/0. Network Routing And Switching , autonomous system is part of the router policy. It is a single network or a combined group of networks We can also use three- or four-level hierarchical routing. In three-level hierarchical routing, the network is classified into a number of clusters. Each cluster is made up of a number of regions, and each region contains a number or routers. Hierarchical routing is widely used in Internet routing and makes use of several routing protocols. Routing in Data Networks 5.1 INTRODUCTION We have frequently referred to the routing algorithm as the network layer protocol that guides packets through the communication subnet to their correct destination. The times at which routing decisions are made depend on whether the network uses datagrams or virtual circuits. Above you can see that R1 knows how to reach the 192.168.2.0/24 network, the next hop IP address is 192.168.12.2. It will now do a second routing table lookup to see if it knows how to reach 192.168.12.2, we call this recursive routing. As you can see, there is an entry for 192.168.12.0/24 with GigabitEthernet 0/2 as the interface to use.

To illustrate static routing the example will be a small network with two routers and two workstations, with the workstations placed on the far ends of the network. On it, the routers are configured so that the FastEthernet 0/0 (fa0/0) interfaces are for the computer side of the network and the FastEthernet 0/1 (fa0/1) interfaces …

Default Routing is a technique in which a router is configured to send all the packets to the same hop device, and it doesn't matter whether it belongs to a particular network or not. A Packet is transmitted to the device for which it is configured in default routing. Introduction to Routing. The whole world is digitalized and connected over the network. Packets, which are the atomic unit of information in packet-switched communication networks, are exchanged between the nodes (a node might be an end device, a router or a data generating device, etc.). The rest field is an identifier for a specific host or network interface. The routing prefix may be expressed in Classless Inter-Domain Routing (CIDR) notation written as the first address of a network, followed by a slash character (/), and ending with the bit-length of the prefix.

Figure 5-2 Corporate Network That Runs Quagga Protocols. The figure shows a corporate network autonomous system that is subdivided into two routing domains, A and B. Arouting domain is an internetwork with a cohesive routing policy, either for administrative purposes or because the domain uses a single routing protocol.
