RIP InTroDuction And ConFiguration in IPv4 "CCNA and CCNP Part-1" By R00t

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
