Cisco BASIC experiment: Static routing

Topology map:

1. Configure IP Address

R1 Configure IP Address:

R1 (config) #int loopback0

%link-5-changed:interface Loopback0, CHANGED state to up
%lineproto-5-updown:line protocol on Interface Loopback0, changed
R1 (config-if) #ip address 1.1.1.1 255.255.255.0
R1 (config-if) #int s2/0

R1 (config-if) #clock rate 128000
R1 (config-if) #ip address 192.168.12.1 255.255.255.0
R1 (config-if) #no shut

Configure R2 IP:

R2 (config) #int loopback0
R2 (config-if) #ip address 2.2.2.2 255.255.255.0
R2 (config-if) #int s2/0
R2 (config-if) #clock rate 128000
R2 (config-if) #ip address 192.168.12.2 255.255.255.0
R2 (config-if) #no shut

R2 (config-if) #int s3/0
R2 (config-if) #clock rate 128000
R2 (config-if) #ip address 192.168.23.2 255.255.255.0
R2 (config-if) #no shut

Configure R3 IP:

R3 (config) #int loopback0
R3 (config-if) #ip address 3.3.3.3 255.255.255.0
R3 (config-if) #int s3/0
R3 (config-if) #clock rate 128000
R3 (config-if) #ip address 192.168.23.3 255.255.255.0
R3 (config-if) #no shut

2. Configure static routing

R1 Configure static Routes:

R1 (config) #ip Route 2.2.2.0 255.255.255.0 s2/0
R1 (config) #ip Route 3.3.3.0 255.255.255.0 s2/0

R2 Configure static Routes:

R2 (config) #ip Route 1.1.1.0 255.255.255.0 s2/0
R2 (config) #ip Route 3.3.3.0 255.255.255.0 s3/0

R3 Configure static Routes:

R3 (config) #ip Route 1.1.1.0 255.255.255.0 s2/0
R3 (config) #ip Route 2.2.2.0 255.255.255.0 s2/0

3. Experimental test

R1:

R1#sh IP route
CODES:C-connected, s-static, I-igrp, R-rip, M-mobile, B-BGP
