Questions and Answers

Explain the concept of routing and its layer in the OSI model.

Routing is the process of path finding from one end to the other. It occurs at layer 3 of the OSI model.

What is the role of IP in routing?

IP performs functions such as searching for a matching host address, searching for a matching network address, and searching for a default entry.

How does a router decide which interface to send a packet out?

Routing is done by an IP router, which searches the routing table and decides which interface to send a packet out.

What is the purpose of routing tables in a router?

Routing tables are consulted by a router to carry out routing. Routing algorithms use the most similar path to route a packet. Signup and view all the answers

What are the key exterior and interior routing protocols mentioned in the text?

The key exterior routing protocol is the Border Gateway Protocol (BGP), and the interior routing protocols include the Routing Information Protocol (RIP), the Open Shortest Path First Routing Protocol (OSPF), and the Enhanced/Interior Gateway Routing Protocol (IGRP/EIGRP).

What is the difference between exterior and interior routing protocols? Provide examples of each type of routing protocol mentioned in the text.

Exterior routing protocols are used to exchange routing information between different autonomous systems, while interior routing protocols are used within a single autonomous system. Examples of exterior routing protocols include Border Gateway Protocol (BGP), and examples of interior routing protocols include Routing Information Protocol (RIP), Open Shortest Path First Routing Protocol (OSPF), and Enhanced Interior Gateway Routing Protocol (EIGRP).

Explain the process of IP routing and the tasks performed by IP.

IP routing involves searching for a matching host address, searching for a matching network address, and searching for a default entry. The tasks performed by IP include path finding from one end to the other, and routing is carried out at layer 3. Signup and view all the answers

How does a router make routing decisions using a routing table?

A router makes routing decisions by consulting/accessing a routing table. The routing table contains information about the available paths and uses routing algorithms to find the most similar path to route a packet based on the given network by its prefix. Signup and view all the answers

What are the responsibilities of IP router in routing a packet?

The responsibilities of an IP router in routing a packet include searching the routing table to find a matching network address, deciding which interface to send the packet out, and handling congestion control and multicasting. Signup and view all the answers

Discuss the role of layer 3 in routing and layer 2 in bridging according to the OSI model.

Routing occurs at layer 3 of the OSI model, where path finding from one end to the other takes place. Bridging, on the other hand, occurs at layer 2 of the OSI model and involves connecting different network segments together within the same network. Signup and view all the answers

Role of IP in Routing

IP performs functions such as searching for a matching host or network address and finding a default route.
