Dynamic Routing

Dynamic  Routing

     -routing is done by protocol

Distance vector routing:

                Protocol  used in DVR is routing information protocol.it has two versions

-RIP version 1

-Rip version 2

RIP version 1:

    It is a classfull routing protocol that is support only FLSM and does not support VLSM.

Belmanford algorithm is used in RIP version 1.

                                                                       If we are using rip version 1 updates are broadcasted  one to all.Broadcasting Id is the universal broadcast ID 255.255.255.255. Maximum hop count is 15.

Metric:

    It means the best part to reach from source to destination.Metric of a RIP is hop count.

RIP Version 2:

           RIP version 2 is a classless Routing protocol  and it support VLSM.maximum RIP version hop count is 15.AD value is 120 and updates are multicasted.multicast range of RIP version IP is 224.0.0.9

Configuration of RIP version 1:

Router(config)# router rip  -press enter

Router(config-router)# network  <network id>

Router(config-router)# exit

Configuration of RIP version 2:

Router(config)# router rip

Router(config-router)# version 2

Router(config-router)# network <network id>

Router(config-router)# exit

                             Network id we have to give directly connected networks in a router,which we configure.

Configuration of this scenario:

Router1(config)# router rip 

Router(config-router)# network  192.168.10.0

Router(config-router)# network 10.0.0.0

Router(config-router)#  exit.

Router2(config)# router rip 

Router2(config-router)# network 192.168.10.0

Router2(config-router)# network 20.0.0.0

 Router(config-router)#exit.
