The materials used in this lab:-
- 2 Cisco Routers with serial interface
- 2 Cables V35-DTE
- Teleco DCE Modem 2 TD-3 604T
- 2 Cables V35-DTE
- 1 Cable RJ11 (modified for the connection of two modems DCE-3)
Configuration for the router TUX
Router> enable
Router # configure terminal
Enter configuration commands, one per line. End with CNTL / Z.
Router (config) # hostname tux
tux (config) # service password-encryption
tux (config) # no ip domain lookup
tux (config) # enable secret class
tux (config) # username password net MyLink
tux (config) # interface serial 0
tux (config-if) # ip address 172.16.0.1 255 255 255 252
tux (config-if) # encapsulation ppp
tux (config-if) # ppp authentication chap
tux (config-if) # no shutdown
tux (config-if) # exit
tux (config) # line console 0
tux (config-line) # logging synchronous
tux (config-line) # password ccisco
tux (config-line) # login
tux (config-line) # line vty 0 4
tux (config-line) # password lcisco
tux (config-line) # login
tux (config-line) # line aux 0
tux (config-line) # password acisco
tux (config-line) # login
Configuration for the router NET
Router> enable
Router # configure terminal
Enter configuration commands, one per line. End with CNTL / Z.
Router (config) # hostname net
net (config) # service password-encryption
net (config) # no ip domain lookup
net (config) # enable secret class
net (config) # username password tux MyLink
net (config) # interface serial 0
net (config-if) # ip address 172.16.0.2 255 255 255 252
net (config-if) # encapsulation ppp
net (config-if) # ppp authentication chap
net (config-if) # no shutdown
net (config-if) # exit
net (config) # line console 0
net (config-line) # logging synchronous
net (config-line) # password ccisco
net (config-line) # login
net (config-line) # line vty 0 4
net (config-line) # password lcisco
net (config-line) # login
net (config-line) # line aux 0
net (config-line) # password acisco
net (config-line) # login
NB We can use a cable V35-V35-DTE and a DCE replacing the two modem DCE-3 (or a cross cable directly), in this case either be configured as DCE serial adding these commands:
Router # configure terminal
Router (config) # interface serial 0
Router (config) # clock rate 64000
