What is RIP (Routing information protocol)?

Explanation

  • Simple protocol to exchange information between the routers.

  • Defines a way for routers, which connect networks using the Internet Protocol (IP), to share information about how to route traffic among networks.

  • RIP, according to Internet Engineering Task Force (IETF) is an Interior Gateway Protocol (IGP), for moving traffic within a larger autonomous system- enterprise’s network with local area networks (LANs) linked through routers.

  • It is an Interior Gateway Protocol (IGP) to distribute routing information within an Autonomous System (AS).

  • Simple vector protocol with many implementations.

    • In vector protocol, routers exchange reachability information with only their nearest neighbors, communicating the sets of destinations they can reach, and the next hop to reach those destinations.

    • On the other hand, link-state IGPs exchange complete routes with one another- link state routers exchange topology information, and calculate their own complete routes locally.

Describe in Detail

Write a function to swap the values of two integers.

Explanation

Program:

  1. #include<stdio.h>
  2. int main()
  3. {
  4.     int x=15y=20;
  5.     x=x+y;
  6.     y=x-y;
  7.     x=x-y;
  8.     printf(“After swapping : x=%dy=%d”, xy);
  9.     return 0;
  10. }
  • Output:

After swapping: x = 20, y = 15
