Lab 01

Objective:

Setup:

1 Site A

Step 1: Install modem to router

RouterA# conf t

RouterA (Config)# interface s0/4

RouterA (Config-if)# physical-layer async

RouterA (Config-if)# no shut

RouterA (Config-if)# exit

RouterA (Config)# line 5

RouterA (Config-line)# login

RouterA (Config-line)# password cisco1

RouterA (Config-line)# autoselect during-login

RouterA (Config-line)# autoselect ppp

RouterA (Config-line)# login local

RouterA (Config-line)# modem InOut

RouterA (Config-line)# modem autocofigure discovery RouterA (Config-line)# transport input all

RouterA (Config-line)# stopbits 1

RouterA (Config-line)# speed 33600

RouterA (Config-line)# flowcontrol hardware

RouterA (Config-line)# exit

Step 2: Create loopback interface for Telnet into Modem RouterA (Config)# interface loopback0

RouterA (Config-if)# ip add 1.1.1.1 255.0.0.0

RouterA (Config-if)# no shut

Step 3: Secure virtual Telnet session

RouterA (Config-if)# line vty 0 4

RouterA (Config-line)# login

RouterA (Config-line)# password cisco2

RouterA (Config-line)# exit

Step 4: Testing connection from Router to Modem RouterA (Config)# exit

RouterA# Telnet 1.1.1.1 2005

Step 5: configure asyn interface

RouterA# conf t

RouterA (config)# interface s0/4

RouterA (config-if)# shutdown

RouterA (config-if)# ip add 192.168.1.1 255.255.255.0
