Configuring RIP version 1 and version 2

Okay guys . The difference between RIP version 1 and version 2 is that ..version 1 is classful ip addressing ,that means it deals with classes by default .if you put in a class C ip address it will assume that there are three network octats.
where as version 2 is class less ip addressing .here this thing doesnt matter .even 10.0.0.0 can have a subnet of 255.255.255.0 .

BASIC RIP CONFIGURATION V(1&2)

According to the recollection of InetDaemon, configuring a Cisco router for a basic RIP configuration would look something like this:

router> enable
  Password:
  router# conf t
  router(config)#interface ethernet 0
  router(config-if)# ip address 192.168.42.1
  router(config-if)# interface ethernet 1
  router(config-if)# ip address 192.168.43.1
  router(config-if)# exit
  router(config)# router rip
  router(config-router)# network 192.168.42.0
  router(config-router)# network 192.168.43.0
  router(config-router)# exit
  router(config-router)# ^z
  router# 

The example above assumes that the interfaces that will be running RIP have internet protocol (ip) on them that fall within the 204.191.42.0, and 204.191.43.0 class C ranges.

THIS WHOLE THING ABOVE GOES FOR VERSION 1..KEEP IN MIND YOU DONT HAV TO SPECIFY ABOUT VERSION 1

where as in VERSION 2 ..THE DIFFERENCE THAT CAN BE OBSERVED IS

router(config)# router rip
  router(config-router)# network 192.168.42.0
  router(config-router)# network 192.168.43.0
  router(config-router)#version 2
  router(config-router)# exit

the only difference when configuring is the command write up for version 2.KEEP IN MIND THE DEFAULT IS VERSION1 ..YOU NEED TO SPECIFY IF USING VERSION 2
