RIP – Routing Information Protocol

RIP

• RIP - Routing Information Protocol
• It is a Distance Vector-Routing Protocol
• It uses metric called hop-count
• Metric is something each protocol uses to calculate the Best-path.
• Hop-count is nothing, but the number of routers the destination is away from the source.
• RIP has a maximum hop-count of 15, Hop-count of 16 is considered to be with Infinite Metric.
• AD Value is 120
• AD (Administrative distance) is some sort of Trust-worthiness,
• Lower the AD value is Best.
• Nowadays, RIP is outdated Routing Protocol, we use EIGRP and RIP instead of RIP.

RIP Versions

• RIP has 2 version
• RIP version 1 
• RIP version 2
• RIP Version 1
• It is a Classful Routing Protocol, It doesn’t supports Classless Routing.
• It uses Broadcast to send Packets
• It doesn’t Supports Authentication.
• Manual Summarization cannot be enabled.
• Version 1 can Send only Version 1 RIP updates, but can receive both Version.
• RIP Version 2
• It supports Classless Routing Protocols.
• Manual summarization can be enabled
• It uses Multicast to send Packet (Multicast IP : 224.0.0.9)
• Supports Authentication.
• Version 2 can only send and receive only Version 2.

• Consider the above scenario, we are now going to configure RIP in these
• Routers, and how to check the RIP configuration.

RIP Configuration

• Go to Configure mode
• Router-0(config )#
• Go to Router configuration mode
• Router-0(config )#router rip
• Router-0(config-router)#network 192.168.12.0 
• Router-0(config-router)#network 1.1.1.1
• Router-0(config-router)#no auto-summary
• Router-0(config-router)#version 2
• Router-0(config-router)#end
• First Command Enables the RIP Configuration
• Second command, we are advertising what are the networks that need to advertised in RIP
• Third command we are disabling auto-summary, so Classless Routing can be done.
• Fourth command, we are Enabling RIP Version 2, by default RIP version 1 only will be enabled.
• Go to Router configuration mode
• Router-1(config )#router rip
• Router-1(config-router)#network 192.168.12.0 
• Router-1(config-router)#no auto-summary
• Router-1(config-router)#version 2
• Router-1(config-router)#end

RIP Verification

This is the routing table of RIP, 

R – RIP Routing Protocol,

1.1.1.1 is the network Segment

120/1 – 120 is AD value of RIP and 1 is metric(Hop-count for RIP – It 

need to pass one Router to reach the destination of 1.1.1.1

That's it
