Routing Information Protocol (RIP) version 1 is a distance vector routing protocol that updates every 30 seconds and uses hop count for routing decisions, with a maximum of 15 hops. It is classful and only supports subnetting with the same subnet mask for all networks, while version 2 supports classless routing and variable length subnet masking (VLSM). RIP utilizes various timers to manage route updates and invalidation, and specific commands are provided for configuring both RIP v1 and v2 on routers.

1. Distance vector/
30 seconds update/
15 hop counts

2. RIP:- ROUTING INFORMATION PROTOCOL
Rip version 1 is a distance vector routing protocol
It sends a complete routing table to all active
interfaces after 30 sec.
RIP only use Hop count tom determine the best way
to find the destination
With maximum hop count = 15
Means the 16th network will be supposed to be
unreachable.
It works well for small networks.
Rip only use classfull routing means we can use
subnetting but the FLSM only { all the networks
must have the same subnet mask}

3. RIP v1 uses four types of the timers to regulate its
performance.
1.Route update timer = 30 sec
2.Route invalid timer = 180 sec
3.Holddown timer = 180 sec
4.Route flush timer = 240 sec
RIP TIMERS

4. RIP TIMERS
1. Route update timer:-
it is typically 30
seconds in which a router sends a complete
copy of the routing table to all neighbors.
2. Route invalid timer:-
when there is
network failure and a router didn`t get any
update about that network for 180 seconds
the router will send update to all neighbors
about the failure of that network.

5. RIP TIMERS
3.Holddown timer:-
The routing update
table received is only store/ hold till the
hold-down timer which is 180 seconds.
means there is any routing update table
received for any route and after that for 180
seconds there is no any other update
received from that side then the table will be
discard.

6. RIP TIMERS
4.Route flush timer:-
it is the time after
which a route is considered as a invalid route
and the routing information about that
route is removed from the routing table and
the information is updated to the all
neighbor routers before the local routing
table is updated.

8. RIP scenario

9. Configuring the RIP routing
To configure the RIP routing the {ROUTER RIP}
command is used. And we just have to mention the
directly connected networks with the router only.
Job of the rip is to automatically find out the all other
networks and advertise the its connecting networks to all
the connected neighbors. RIP v1 is classfull because the
subnet mask in all the networks is same.

10. Configure RIPv1
On router A
Router_A#config t
Router_A(config)# router rip
Router_A(config)# network 10.0.0.0
Router_A(config)# network 11.0.0.0
Router_A(config)#exit
Router_A#wr
On router B
Router_B#config t
Router_B(config)# router rip
Router_B(config)# network 12.0.0.0
Router_B(config)# network 11.0.0.0
Router_B(config)#exit
Router_B#wr

11. Verify the RIP v1
In each routers routing table there must be a
route for the directly connected networks as well
as routes from the directly connected neighbors.
To verify
Router_A# show ip route
Router_A# show ip protocols

12. Configuring the RIP version 2
While configuring the RIP verison 2 just remember that
RIP 2 use the classless subnetting scheme.
And we can save more Ips using the RIPv2
So do the addressing with VLSM for RIP 2
And follow the NEXT….

13. RIP v2

14. Configuring the RIP v2
A# config t
A(config )# router rip
A(config-router)# version 2
A(config-router)#network 10.0.0.0 255.255.255.252
A(config-router)# network 10.0.0.16 255.255.255.242
A(config-router)#exit
A# wr
B# config t
B(config )# router rip
B(config-router)# version 2
B(config-router)#network 10.0.0.24 255.255.255.252
B(config-router)# network 10.0.0.16 255.255.255.242
B(config-router)#exit
B# wr
