Hybrid Routing

Hybrid Routing

         Protocol  used in hybrid routing is EIGRP.[Enhance Interior Gateway Protocol].It is a cisco proprietory protocol.

Algorithm:

      EIGRP is using dual algorithm.updates are multicasted.Multicasting address is 224.0.0.10.updates are even triggered. maximum hop count is 255.but default value is 100.it ia classless protocol.metric of EIGRP is composit metric.EIGRP maintaining tables are

1.       Neighbour Table

2.       Topology Table

3.       Routing Table

Syntax:

Router(config)# Router eigrp <as number>

[Autonomous Number range is 1-65,535- as number can give any number between 1-65,535

Different as number in different router will not communicate,same as number in different router will only communicate.]

Router(config-router)# network network id

Router(config-router)# exit

[Network id should be  give directly conneted networks]

In this scenario configuration is.

Router1(config)# router eigrp 1

Router(config-router)#  network  192.168.10.0

Router(config-router)#  network  10.0.0.0

Router(config-router)#  exit

Router2(config)  router eigrp 1

Router(config-router)#  network 192.168.10.0

Router(config-router)#  network 192.168.20.0

Router(config-router)#  network 20.0.0.0

Router3(config) router eigrp 1

Router(config-router)#  network 192.168.20.0

Router(config-router)#  network 30.0.0.0

Router(config-router)#  exit
