Routing Information Protocol (RIP)

Steering Information Protocol (RIP) was the primary convention utilized in unique directing. Albeit present day systems don't utilize it today, it's as yet well known in little systems in light of its straightforwardness and in scholarly conditions as a beginning stage of seeing how the directing procedure is functioning. In this way why Cisco remembers it for the CCNA test.

Tear is a separation vector steering convention. As all steering conventions are utilizing a measurement, the one utilized by RIP is the jump check. The most limited the jump check, the almost certain RIP will picked that way to arrive at the goal organize. Be that as it may, RIP's most extreme bounce tally is 15(CCNA test question). Any course with a bounce tally more noteworthy than 15 is viewed as inaccessible. Steering refreshes are communicated as a matter of course at regular intervals. They are sent in UDP bundles with both source and goal port numbers set to 520. Since the greatest datagram size is just 504 bytes, there's a limit of 25 courses that can be reported in a solitary bundle. Having more courses will make the switch send more parcels.

There are just two message types utilized by RIP. Solicitation message and Response message. The names are as enlightening as they can be. At the point when a RIP empowered switch interface comes up, it conveys a Request message. The other RIP empowered switches in the system are reacting with Response messages. At the point when the principal switch gets the Response messages, it introduces the new gotten courses in it's steering table. In the event that the switch as of now has a course in it's table however it shows signs of improvement jump check, the old course is supplanted. From that point onward, the switch sends its own steering table to its neighbors.

The default Administrative Distance for RIP is 120(another CCNA test question). In steering, the AD is utilized as a kind of perspective of reliability. The lower the worth, the higher the need of that course. For instance, in the event that you have a course gotten through RIP, which has an AD of 120, and you have a similar course gotten from a help desk support salaries higher need convention like OSPF, which has a default AD of 110, OSPF will be in control to course the bundles through its course, regardless of whether the directing convention metric is more noteworthy. Because of its absence of scaling abilities, RIP is the least-favored convention from all Interior Gateway Protocols
