Learn Linux CCNA CEH IPv6 Cyber-Security Online

This is basic networking tutorial showing ip address configuration on cisco router.For demonstration i have used cisco packet tracer software.For this ip address configuration lab I have taken three routers and two PC and total four Networks. 1.0.0.0/8   3.0.0.0/8    4.0.0.0/8  and  5.0.0.0/8. Along with ip assignment on router interfaces we will also learn how to change host-name on router.

STEP 1:IP Address Configuration on Router R1:

Router(config)#host r1

r1(config)#int fa0/0

r1(config-if)#ip add 1.0.0.1 255.0.0.0

r1(config-if)#no shut

r1(config-if)#exit

r1(config)#int fa0/1

r1(config-if)#ip add 3.0.0.1 255.0.0.0

r1(config-if)#no shut

STEP 2: IP ADDRESS Configuration on Router r2:

Router>enable

Router#config t

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#host r2

r2(config)#int fa0/0

r2(config-if)#ip add 3.0.0.2 255.0.0.0

r2(config-if)#no shut

r2(config-if)#exit

r2(config)#int fa0/1

r2(config-if)#ip add 4.0.0.1 255.0.0.0

r2(config-if)#no shut

STEP 3:IP Address Configuration on router r3:

Router>enable

Router#config t

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#host r3

r3(config)#int fa0/0

r3(config-if)#ip add 4.0.0.2 255.0.0.0

r3(config-if)#no shut

r3(config-if)#exit

r3(config)#int fa0/1

r3(config-if)#ip add 5.0.0.1 255.0.0.0

r3(config-if)#no shut
