EIGRP configuration Lab having Two Routers and Both having same autonomous system number.


In this lab is have shown how to configure EIGRP in very simple way. This is the simplest method to configure EIGRP on cisco routers.


In EIGRP we tell Routers about Directly Connected Networks.


Autonomous System(AS):is a group of networks under a single administrative control.


An AS can be a ISP or a large Enterprise Organization.


IGP handles Routing Within AS(Autonomous System)


IGP Includes RIP,IGRP,EIGRP and OSPF


Note:EGP handles routing between AS.

BGP is the obly EGP.

 UNDERSTAN AUTONOMOUS SYSTEM(AS)


Autonomous System Number(ASN) is a 16bit binary number and we can represent it as 2^16 numbers which is equal to 65536.

Range of ASN 0 to 65535


0-65535 Reserved


1-64511 Internet Routing – ISP AS


64512-65534 Private Use- Private AS


EIGRP Configuration on Router R1:

 

R1(config)#router eigrp 1

R1(config-router)#network 1.0.0.0

R1(config-router)#network 2.0.0.0

R1(config-router)#exit

 

EIGRP Configuration on Router R2:

R2(config)#router eigrp 1

R2(config-router)#network 2.0.0.0

R2(config-router)#network 3.0.0.0

R2(config-router)#

 

 

Static routing configuration Lab using two Routers and Having three Networks.


We are going to configure static route between router R1 and R2 in this lab with the help of cisco packet tracer.

In static routing Configuration we have to tell the Routers about Indirectly Connected Networks. Although static routing configuration is so complex when network is too big or number of routers are so much.

It is practically not feasible to implement static routing in big companies where there are so many routers. In that case you can use Dynamic Routing like RIP Routing,EIGRP and OSPF.

RIP Routing Lab Having Two Routers and Total Three Network- A cisco Packet Tracer Lab CCNA.

RIP configuration using Two routers using cisco packet tracer. This is an easy example to show how to configure RIP on Cisco Routers.

RIP routing is used by Small and Mid Level companies. There is no difference in RIPv1 and RIPv2 Configuration.

In RIP routing we just have to mention the directly connected Network.
