RIP Introduction and Configuration in IPv4 {CCNA and CCNP Part-1}

 

Ø  VLSM(Variable Length Subnet Mask}:-Send the Network with their Subnet Mask

Ø  Algorithm First Developed In 1969!!!

                                                                                                               

Ø  Split Horizon:- Do not Send update for an interface that interface you receive the update

Ø  Poison Reverse:- if Routers any interfaces down it will update their neighbor that network is unreachable using metric {hop count} 16

Ø  Hop Count:- Rip Choose Best path using hop (router) count. Rip support only 15 hop 16 is unreachable

Ø  Full and Triggered Updates:- Rip Send their Routing table every 30 Seconds and it send Full update and if any network is added or down then it send Triggered update

Ø  RIP Update Timer:-every 30 Seconds

Ø  Rip Hold Timer:- 180 Seconds  {3minutes}

Ø  Flush Timer:- 240 Seconds  {4 minutes}

v  R1 interfaces Configuration:-

Ø  R1(config)#interface serial 1/0

Ø  R1(config-if)#description CONNECTED WITH R2

Ø  R1(config-if)#ip address 192.168.1.1 255.255.255.252

Ø  R1(config-if)#clock rate 64000

Ø  R1(config-if)#no shut

Ø  R1(config-if)#exit

Ø  R1(config)#interface fastEthernet 0/0

Ø  R1(config-if)#description CONNECTED WITH SW1

Ø  R1(config-if)#ip address 192.168.2.1 255.255.255.0

Ø  R1(config-if)#no shut

Ø  R1(config-if)#exit

v  R2 interfaces Configuration:-

Ø  R2(config)#interface serial 1/0

Ø  R2(config-if)#description CONNECTED WITH R1

Ø  R2(config-if)#ip address 192.168.1.2 255.255.255.252

Ø  R2(config-if)#no shut

Ø  R2(config-if)#exit

Ø  R2(config)#interface serial 1/1

Ø  R2(config-if)#description CONNECTED WITH R3

Ø  R2(config-if)#ip address 192.168.1.5 255.255.255.252

Ø  R2(config-if)#clock rate 64000

Ø  R2(config-if)#no shut

Ø  R2(config-if)#exit

v  R3 interfaces Configuration:-

Ø  R3(config)#interface fastEthernet 0/0

Ø  R3(config-if)#description CONNECTED WITH SW2

Ø  R3(config-if)#ip address 10.250.250.1 255.255.255.0

Ø  R3(config-if)#no shut

Ø  R3(config-if)#exit

Ø  R3(config)#interface serial 1/1

Ø  R3(config-if)#description CONNECTED WITH R2

Ø  R3(config-if)#ip address 192.168.1.6 255.255.255.252

Ø  R3(config-if)#no shut

Ø  R3(config-if)#exit

v  RIP Configuration

Ø  R1(config)#router rip                                  {Turns On Routing Protocols)

Ø  R1(config-router)#version 2          

Ø  R1(config-router)#network 192.168.1.0        

Ø  R1(config-router)#network 192.168.2.0

Ø  R1(config-router)#no auto-summary              {Do not Summarize These network as their Default Class network}              

Ø  R1(config-router)#exit

ü  Network:-Tells Rip What Network you advertise

ü  And Tells Rip What Interface you Send Hello msg.

Ø  R2(config-router)#version 2

Ø  R2(config-router)#network 192.168.1.4

Ø  R2(config-router)#network 192.168.1.0

Ø  R2(config-router)#no auto-summary

Ø  R2(config-router)#exit

Ø  R3(config)#router rip

Ø  R3(config-router)#version 2

Ø  R3(config-router)#network 10.250.250.0

Ø  R3(config-router)#network 192.168.1.4

Ø  R3(config-router)#no auto-summary                  {Do not Summarize These network as their Default Class network}

Ø  R3(config-router)#exit

v  Troubleshooting & Verification Commands

Ø  Show ip route

Ø  Show ip protocols

Ø  Debug ip rip {option}

v  Now Test
