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
Authentication
Password: cisco1
<test some AT commands >
ATDT<phonenumber of remote site>
AT&W
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
RouterA (config-if)# encapsulation ppp
RouterA (config-if)# async mode dedicated
RouterA (config-if)# no cdp enable
RouterA (config-if)# dialer in-band
RouterA (config-if)# dialer idle-timeout 300
RouterA (config-if)# dialer wait-for-carrier-time 60
RouterA (config-if)# dialer hold-queue 50
RouterA (config-if)# dialer group 1
RouterA (config-if)# dialer map ip 192.168.1.2 name SiteB modem-script TaiA broadcast
204
RouterA (config-if)# exit
RouterA (config)# chat-script REMDEVICE ABORT ERROR ABORT BUSY “” “ATZ”
OK “ATDT \T” TIMEOUT 30 CONNECT \c
RouterA (config)# dialer-list 1 protocol ip permit
RouterA (config)# ip route 0.0.0.0 0.0.0.0 192.168.1.2

Step 5: configure asyn interface
RouterB# conf t
RouterB (config)# interface ASYNC 0 (???)
RouterB (config-if)# shutdown
RouterB (config-if)# ip add 192.168.1.2 255.255.255.0

RouterB (config-if)# dialer wait-for-carrier-time 60
RouterB (config-if)# dialer hold-queue 50
RouterB (config-if)# dialer group 1
RouterB (config-if)# dialer map ip 192.168.1.1 name Sitea modem-script TaiB broadcast
