\nWhat is RIP protocol?<\/strong>
\nIt\u2019s a distance-vector routing protocol<\/strong> used to send data from one router to another within a network<\/strong> (aka intra-domain). It chooses paths based on one thing: hop count<\/strong> \u2013 how many routers the data must jump through to reach the destination.<\/p>\n<\/blockquote>\n![\"RIP](\"https:\/\/www.kaashivinfotech.com\/blog\/wp-content\/uploads\/2025\/06\/RIP-Protocol-Example.png\")

\n- RIP protocol full form<\/strong>: Routing Information Protocol<\/em><\/li>\n
- Hop<\/strong>: A hop is like passing your friend a note via other classmates. Every time the note passes through someone else, that\u2019s 1 hop.<\/li>\n<\/ul>\n
So if Router A sends a packet to Router D through B and C? That\u2019s 3 hops.
\nRIP says: \u201cCool. I\u2019ll take that route.\u201d<\/em>

<\/a>How Does RIP Protocol Work?<\/figcaption><\/figure>\n
\n\ud83e\udde9 How Does RIP Protocol Work? (And Why Should You Care?)<\/strong><\/h2>\nLet\u2019s simplify.<\/p>\n
RIP works by:<\/p>\n
\n- Broadcasting<\/strong> its entire routing table to neighboring routers every 30 seconds<\/strong>.<\/li>\n
- Each router updates its table based on the shortest (hop count-wise) path.<\/li>\n
- If no update is received within 180 seconds<\/strong>, the route is marked as invalid<\/em>.<\/li>\n
- If there’s still no response by 240 seconds<\/strong>, the route is flushed out<\/em>.<\/li>\n<\/ol>\n
\n\ud83d\udcc9 That\u2019s a 4-minute delay<\/strong> before RIP realizes something went wrong in the network. That\u2019s ancient in 2025.<\/p>\n<\/blockquote>\nNow, imagine using this in a real-time multiplayer game. Yeah, lag city<\/em>. That\u2019s why RIP protocol in networking<\/strong> is mainly used in labs<\/strong>, academic projects<\/strong>, or mock interview questions<\/strong>, not in large-scale enterprise networks.<\/p>\n <\/p>\n
\n\ud83d\udd0d RIP Protocol in Computer Networks \u2013 An Example<\/strong><\/h2>\nSuppose 4 routers (R1 to R4) are connected in a line.<\/p>\n
\n- R1 \u2192 R2 \u2192 R3 \u2192 R4<\/li>\n
- This is 3 hops.<\/li>\n<\/ul>\n
If R1 wants to send data to R4, RIP checks how many routers it has to go through. If there are multiple paths<\/strong> with the same hop count, RIP sends traffic down both paths<\/strong> to balance the load.<\/p>\n\u2705 Load balancing<\/strong>
\n\u274c No idea if one path is congested or faster
\nTo give a good example:
\n<\/strong><\/p>\nImagine every post office knows how to send mail to every other post office. To do this, it keeps a list showing:<\/p>\n
\n- \n
Where the mail is going (the destination)<\/p>\n<\/li>\n
- \n
Which nearby post office to send it through (the next stop)<\/p>\n<\/li>\n
- \n
How many post offices (hops) it takes to get there<\/p>\n<\/li>\n<\/ul>\n
Every 30 minutes, each post office tells its neighbors what it knows. When a neighbor hears this:<\/p>\n
\n- \n
It adds 1 to the number of hops (since the mail has to pass through that neighbor now)<\/p>\n<\/li>\n
- \n
If this new route is shorter than what it already knows, it updates its list<\/p>\n<\/li>\n
- \n
If the route takes more than 15 hops, it gives up and marks it as unreachable<\/p>\n<\/li>\n<\/ul>\n
