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)#
