Configuration of Routing Information Protocol

Routing Information Protocol (RIP) is a dynamic routing protocol which uses hop count as a routing metric to find the best path between the source and the destination network. It is a distance vector routing protocol which has AD value 120 and works on the application layer of OSI model. RIP uses port number 520.

Features of RIP

1. Updates of the network are exchanged periodically.
2. Updates (routing information) are always broadcast.
3. Full routing tables are sent in updates.
4. Routers always trust on routing information received from neighbor routers. This is also known as Routing on rumours.

RIP versions :
There are three vesions of routing information protocol – RIP Version1, RIP Version2 and RIPng.

RIP v1 is known as Classful Routing Protocol because it doesn’t send information of subnet mask in its routing update.
RIP v2 is known as Classless Routing Protocol because it sends information of subnet mask in its routing update.

Configuration :

1> Configure RIP for R1

R1(config)# router rip
R1(config-router)# network 192.168.20.0
R1(config-router)# network 172.16.10.4
R1(config-router)# version 2
R1(config-router)# no auto-summary

3> Configureg RIP for R2

R2(config)# router rip
R2(config-router)# network 192.168.10.0
R2(config-router)# network 172.16.10.0
R2(config-router)# version 2

R2(config-router)# no auto-summary

3>
R3(config)# router rip
R3(config-router)# network 10.10.10.0
R3(config-router)# network 172.16.10.4
R3(config-router)# network 172.16.10.0
R3(config-router)# version 2

R3(config-router)# no auto-summary

Packet Tracer Simulation – TCP and UDP Communications Part 1: Generate Network Traffic in Simulation Mode Step 1: Generate traffic to populate Address Resolution Protocol (ARP) tables. Click MultiServer and click the Desktop tab > Command Prompt. Enter the ping 192.168.1.255 command. This will take a few seconds as every device on the network responds to MultiServer. Close the MultiServer window. Step 2: Generate web (HTTP) traffic. Switch to Simulation mode. Click HTTP Client and click the Desktop tab > Web Browser. In the URL field, enter 192.168.1.254 and click Go. Envelopes (PDUs) will appear in the simulation window. Minimize, but do not close, the HTTP Client configuration window. Step 3: Generate FTP traffic. Click FTP Client and click the Desktop tab > Command Prompt. Enter the ftp 192.168.1.254 command. PDUs will appear in the simulation window. Minim...

Networking – SocketProgramming in TCP. Python provides two levels of access to network services. At a low level, you can access the basic socket support in the underlying operating system, which allows you to implement clients and servers for both connection-oriented and connectionless protocols. Python also has libraries that provide higher-level access to specific application-level network protocols, such as FTP, HTTP, and so on. What is Sockets? Sockets are the endpoints of a bidirectional communications channel. Sockets may communicate within a process, between processes on the same machine, or between processes on different continents. Sockets may be implemented over a number of different channel types: Unix domain sockets, TCP, UDP, and so on. The socket library provides specific classes for handling the common transports as well as a generic interface for handling the rest. Sockets have their own vocabulary − ...

IMPLEMENTATION OF DHCP IN CISCO PACKET TRACER The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used on UDP/IP networks whereby a DHCP server dynamically assigns an IP address and other network configuration parameters to each device on a network so they can communicate with other IP networks. A DHCP server enables computers to request IP addresses and networking parameters automatically from the Internet service provider (ISP), reducing the need for a network administrator or a user to manually assign IP addresses to all network devices.In the absence of a DHCP server, a computer or other device on the network needs to be manually assigned an IP address, or to assign itself an APIPA address, which will not enable it to communicate outside its local subnet. DHCP can be implemented on networks ranging in size from home networks ...
