Routing Information Protocol

Distance vector/30 seconds update/

15 hop counts

RIP:- ROUTING INFORMATION PROTOCOL

Rip version 1 is a distance vector routing protocolIt 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 destinationWith 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}

RIP v1 uses four types of the timers to regulate its performance.

1.Route update timer = 30 sec2.Route invalid timer = 180 sec3.Holddown timer = 180 sec4.Route flush timer = 240 sec

RIP TIMERS

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.

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.

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.

RIP scenario

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.

Configure RIPv1On router ARouter_A#config tRouter_A(config)# router ripRouter_A(config)# network 10.0.0.0Router_A(config)# network 11.0.0.0Router_A(config)#exitRouter_A#wr

On router B

Router_B#config tRouter_B(config)# router ripRouter_B(config)# network 12.0.0.0Router_B(config)# network 11.0.0.0Router_B(config)#exitRouter_B#wr

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 routeRouter_A# show ip protocols

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….
